[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] Mitigation: Inject CSS user styles to enforce cosmetic filtering
Related issues:
- https://github.com/uBlockOrigin/uBOL-issues/issues/5#issuecomment-1575425913
- https://github.com/w3c/webextensions/issues/403

Currently, there is no other way to inject CSS user styles than to
wake up the service worker, so that it can inject the CSS styles
itself using the `scripting.insertCSS()` method.

If ever the MV3 API supports injecting CSS user styles directly
from a content script, uBOL will be back to be fully declarative.

At this point the service worker is very lightweight since the
filtering is completely  declarative, so this is not too much of
an issue performance-wise except for the fact that waking up the
service worker for the sole purpose of injecting CSS user styles
and nothing else introduces a pointless overhead.

Hopefully the MV3 API will mature to address such inefficiency.

[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).

[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.
