[mv3] Add support for admin configurations
See `managed_storage.json` for available settings. Currently
only `noFiltering` setting is availale.

`noFiltering` is an array of strings, each being a domain for
which no filtering should occur.

[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] 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 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 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.
