[mv3] Add minimal ability to diagnose ruleset issue
A new icon has been added to the popup panel, to open a popup
window with a terse list of DNR events for the current tab, in
reverse chronological order (most recent DNR event appears at
the top).

The new ability is available only when the extension is sideloaded,
as per `declarativeNetRequestFeedback` documentation. Ref:
https://developer.chrome.com/docs/extensions/reference/api/declarativeNetRequest#event-onRuleMatchedDebug

Purposefully minimal, so as to have something rather than nothing
when having to diagnose filtering issue with the DNR API. Example:
https://github.com/uBlockOrigin/uBOL-home/issues/156

The content of the popup window does not dynamically update, force
a refresh (F5) to get the most recent DNR events. This might be
improved in the future.

The DNR event buffer is not persisted, so the buffer is empty when
service worker is restarted. This might be improved in the future
by using session storage API.

There is no output filtering ability in this first draft. This
might be improved in the future.

DNR rules are reported. The filter from which a DNR rule
originates is not reported. Given that the rulesets are optimized
after conversion from original filter lists to reduce the DNR rule
count, this is unlikely to ever be possible.

[mv3] Fix issue with updateContentScripts API and other fixes
Avoid using updateContentScripts() as it suffers from an unexpected
behavior, causing injected content scripts to lose proper order
at injection time. The order in which content scripts are injected
is key for uBOL content scripts. Potential out of order injection
was causing cosmetic filtering to be broken.

Use actual storage API to persist data across service worker
wake-ups and browser launches. uBOL was trying to avoid using
storage API, at the cost of somewhat hacky code (using DNR API
to persist settings).

Make use of session storage if available, to speed up
initialization of waking up the service worker (which at this
point is necessary to properly implement cosmetic filtering).

[mv3] Refactor content scripts related to specific cosmetic filtering
Specifically, avoid long list of hostnames for the `matches`
property[1] when registering the content scripts, as this was causing
whole browser freeze for long seconds in Chromium-based browsers
(reason unknown).

The content scripts themselves will sort out which cosmetic filters to
apply on which websites.

This change makes it now possible to support annoyances-related lists,
and thus two lists have been added:
- EasyList -- Annoyances
- EasyList -- Cookies

Related issue:
- https://github.com/uBlockOrigin/uBOL-issues/issues/5

These annoyances-related lists contains many thousands of specific
cosmetic filters and as a result, before the above change this was
causing long seconds of whole browser freeze when simply modifying
the blocking mode of a specific site via the slider in the popup
panel.

It is now virtually instantaneous, at the cost of injecting larger
cosmetic filtering-related content scripts (which typically should
be garbage-collected within single-digit milliseconds).

Also, added support for entity-based cosmetic filters. (They were
previously discarded).

Code maintenance: replace uDom.js with dom.js
`uDom` is old and crusty and `dom` is meant as replacement. The
goal of `dom` is to be simpler and mainly just convenience
methods for handling the DOM with vanilla JS -- this is not a
framework.

Additionally, removed keyboard shortcuts pane which was useful
only on very old versions of Firefox.

[mv3] Add support for csp= filters
Network filters with csp= option will now be enforced.

Caveat: DNR API does not have support for exception csp= rules,
so excepted csp= filters are currently rejected at conversion time.

[mv3] Add ability to handle entity-based CSS and scriptlet injection filters
This commit adds the ability to inject entity-based plain CSS
filters and also a set of the most commonly used entity-based
scriptlet injection filters.

Since the scripting API is not compatible with entity patterns,
the entity-related content scripts are injected in all documents
and the entity-matching is done by the content script themselves.

Given this, entity-based content scripts are enabled only when
working in the Complete filtering mode, there won't be any
entity-based filters injected in lower modes.

Also, since there is no way to reasonably have access to the
Public Suffix List in the content scripts, the entity-matching
algorithm is an approximation, though I expect false positives
to be rare (time will tell). In the event of such false
positive, simply falling back to Optimal mode will fix the
issue.

The following issues have been fixed at the same time:

Fixed the no-filtering mode related rules having lower priority
then redirect rules, i.e. redirect rules would still be applied
despite disabling all filtering on a site.

Fixed improper detection of changes to the generic-related CSS
content script, potentially causing undue delays when for example
trying to access the popup panel while working in Complete mode.
The scripting MV3 can be quite slow when registering/updating
large content scripts, so uBOL does its best to call the API only
if really needed, but there had been a regression in the recent
builds preventing uBO from properly detecting unchanged content
script parameters.

[mv3] Add support for redirect= filters
This adds support for `redirect=` filters. As with `removeparam=`
filters, `redirect=` filters can only be enforced when the
default filtering mode is set to Optimal or Complete, since these
filters require broad host permissions to be enforced by the DNR
engine.

`redirect-rule=` filters are not supported since there is no
corresponding DNR syntax.

Additionally, fixed the dropping of whole network filters even though
those filters are still useful despite not being completely
enforceable -- for example a filter with a single (unsupported) domain
using entity syntax in its `domain=` option should not be wholly
dropped when there are other valid domains in the list.

[mv3] Add support for removeparam= filter option
Consequently, AdGuard URL Tracking Protection (AUTP) has been
added to the set of available filter lists.

However, removeparam= equivalent DNR rules can only be enforced
when granting uBOL broad permissions. If broad permissions are
not granted, removeparam= equivalent DNR rules are ignored.

Exception removeparam= filters are not supported, and these are
present in AUTP and meant to unbreak some websites which are
known to break as a result of removing query parameters.

This is issue might be mitigated in the future by making the
conversion from filters to DNR rules more complicated but this
can never replace the accuracy of uBO's filtering engine being
able to fully enforce arbitrary exception removeparam= filters.

Also, it is not possible to translate regex-based removeparam=
values to DNR rules, so these are dropped at conversion time.

As with other filters to DNR rules conversion, the converter
coallesce many distinct removeparam= filters into fewer DNR
rules.

[mv3] Add support for specific cosmetic filtering
Specific plain CSS cosmetic filters are now supported.

Cosmetic filtering will occur only after the user explicitly
grant uBO extended permissions for a given site, so that it
can inject CSS on the site.

A new button in the popup panel allows a user to grant/revoke
extended permissions to/from uBO Lite for the current site.

More capabilities will be carefully added for when extended
permissions are granted on a site, so specific cosmetic
filtering through plain CSS is the first implemented capability.

Generic and procedural cosmetic filtering is not implemented.

The current implementation for plain CSS cosmetic filters is
through declarative content injection, which does not require
the service worker to be alive, the browser takes care to
inject the cosmetic filters.

However declarative CSS injection does not support user
styles, so the injected cosmetic filters are "weak". I consider
this is a browser issue, since user styles are supported by
Chromium, there is just no way in the API to specify user
styles for the injected content.

Also:
- Fixed dark theme issues
- Added Steven Black's hosts file

Keep in mind all this is very experimental and implementation
details in this release may (will) greatly change in the future.
