Procedural cosmetic exception filters were the
last class of cosmetic exception filters not
being reported in the logger; this commit fixes
this.
Additionally, ensure that a single DOM listener
can't prevent other listeners from being
processed by throwing an exception. Such approach
would have prevented regression leading to
emergency release 1.22.4:

In rare circumstances, it's possible the content
script lose access to the background page, best
to check against this to avoid spurious console
errors.
Using pairs of integers allows the use of a
single integer-only array to store lists of
string indices associated to a specific
hostname.
Memory usage of instances of HostnameBasedDB
as per Chromium's heap snaphshot (bytes):
Before:
2,459,256 => specific cosmetic filters
944,152 => scriptlet filtering

---------
3,404,144
After:
1,947,448 => "
757,936 => "

Ultimately, using 2 integers for each entry
instead of a single one is still worth it
because this allows the use of one single
integer-only array instead of having to use
an array of arrays for hostnames which have
multiple entries.
This commits make it so that `csp=` filters
are now stored in the same data structures as
all other static network filters rather than
being stored in a separate one.
This internal change is motivated by the wish
to bring session filters to the static network
filtering engine, as has already been done for
the static extended filtering engine in the
following commit:

Ensure that the code which depends on extending
`vapi-client.js` is ready to deal with
`vapi-client-extra.js` failing to load.
This is a feature under development, hidden behind
a new advanced setting, `filterAuthorMode` which
default to `false`.
Ability to point-and-click to create temporary
exception filters for static extended filters (i.e.
cosmetic, scriptlet & html filters) from within
the summary pane in the logger. The button to
toggle on/off temporary exception filter is
labeled `#@#`.
The created exceptions are temporary and will be
lost when restarting uBO, or manually toggling off
the exception filters.
Creating temporary exception filters does not
cause the filter lists to reloaded, and thus there
is no overhead in creating/removing these temporary
exception filters.
These spurious error messages can occur when a
extension framework API method return a
rejected Promise. In uBO the results of
browserAction methods is not used so it can be
safely discarded.

For static filter `popup` filter purpose, the URL of the
embedded frame from which the popup was launched will
be used in the matching algorithm.
As reported by https://github.com/uBlock-user,
adding the two following filters:
example.com##div:style(width: 1016px !important)
example.com##div:style(display: block !important)
The logger would report only one of the filter when
navigating to https://example.com/
