Add experimental mv3 version

This create a separate Chromium extension, named
"uBO Minus (MV3)".

This experimental mv3 version supports only the blocking of
network requests through the declarativeNetRequest API, so as
to abide by the stated MV3 philosophy of not requiring broad
"read/modify data" permission. Accordingly, the extension
should not trigger the warning at installation time:

    Read and change all your data on all websites

The consequences of being permission-less are the following:

- No cosmetic filtering (##)
- No scriptlet injection (##+js)
- No redirect= filters
- No csp= filters
- No removeparam= filters

At this point there is no popup panel or options pages.

The default filterset correspond to the default filterset of
uBO proper:

Listset for 'default':
  https://ublockorigin.github.io/uAssets/filters/badware.txt
  https://ublockorigin.github.io/uAssets/filters/filters.txt
  https://ublockorigin.github.io/uAssets/filters/filters-2020.txt
  https://ublockorigin.github.io/uAssets/filters/filters-2021.txt
  https://ublockorigin.github.io/uAssets/filters/filters-2022.txt

  https://easylist.to/easylist/easyprivacy.txt
  https://malware-filter.gitlab.io/malware-filter/urlhaus-filter-online.txt
  https://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&showintro=1&mimetype=plaintext

The result of the conversion of the filters in all these
filter lists is as follow:

Ruleset size for 'default': 22245
  Good: 21408
  Maybe good (regexes): 127
  redirect-rule= (discarded): 458
  csp= (discarded): 85
  removeparams= (discarded): 22
  Unsupported: 145

The fact that the number of DNR rules are far lower than the
number of network filters reported in uBO comes from the fact
that lists-to-rulesets converter does its best to coallesce
filters into minimal set of rules. Notably, the DNR's
requestDomains condition property allows to create a single
DNR rule out of all pure hostname-based filters.

Regex-based rules are dynamically added at launch time since
they must be validated as valid DNR regexes through
isRegexSupported() API call.

At this point I consider being permission-less the limiting
factor: if broad "read/modify data" permission is to be used,
than there is not much point for an MV3 version over MV2, just
use the MV2 version if you want to benefit all the features
which can't be implemented without broad "read/modify data"
permission.

To locally build the MV3 extension:

    make mv3

Then load the resulting extension directory in the browser
using the "Load unpacked" button.

From now on there will be a uBlock0.mv3.zip package available
in each release.
