Add ability to control trusted status of filter lists
Related discussion:
https://github.com/uBlockOrigin/uBlock-issues/discussions/2895

Changes:

The _content of the My filters_ pane is now considered untrusted by
default, and only uBO's own lists are now trusted by default.

It has been observed that too many people will readily copy-paste
filters from random sources. Copy-pasting filters which require trust
represents a security risk to users with no understanding of how the
filters work and their potential abuse.

Using a filter which requires trust in a filter list from an untrusted
source will cause the filter to be invalid, i.e. shown as an error.

A new advanced setting has been added to control which lists are
considered trustworthy: `trustedListPrefixes`, which is a space-
separated list of tokens. Examples of possible values:

- `ublock-`: trust only uBO lists, exclude everything else including
  content of _My filters_ (default value)

- `ublock- user-`: trust uBO lists and content of _My filters_

- `-`: trust no list, essentially disabling all filters requiring
  trust (admins or people who don't trust us may want to use this)

One can also decide to trust lists maintained elsewhere. For example,
for stock AdGuard lists add ` adguard-`. To trust stock EasyList lists,
add ` easylist-`.

To trust a specific regional stock list, look-up its token in
assets.json and add to `trustedListPrefixes`.

The matching is made with String.startsWith(), hence why `ublock-`
matches all uBO's own filter lists.

This also allows to trust imported lists, for example add
` https://filters.adtidy.org/extension/ublock/filters/` to trust all
non-stock AdGuard lists.

Add the complete URL of a given imported list to trust only that one
list.

URLs not starting with `https://` or `file:///` will be rejected,
i.e. `http://example.org` will be ignored.

Invalid URLs are rejected.

uBlock Origin (uBO)

BEWARE! uBO is (and has always been) COMPLETELY UNRELATED to the website ublock.org.

uBlock Origin (uBO) is a CPU and memory-efficient wide-spectrum content blocker for Chromium and Firefox. It blocks ads, trackers, coin miners, popups, annoying anti-blockers, malware sites, etc., by default using EasyList, EasyPrivacy, Peter Lowe's Blocklist, Online Malicious URL Blocklist, and uBO filter lists. There are many other lists available to block even more. Hosts files are also supported. uBO uses the EasyList filter syntax and extends the syntax to work with custom rules and filters.

You may easily unselect any preselected filter lists if you think uBO blocks too much. For reference, Adblock Plus installs with only EasyList, ABP filters, and Acceptable Ads enabled by default.

It is important to note that using a blocker is NOT theft. Do not fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalization of the inalienable right to privacy.

Ads, "unintrusive" or not, are just the visible portion of the privacy-invading means entering your browser when you visit most sites. uBO's primary goal is to help users neutralize these privacy-invading methods in a way that welcomes those users who do not wish to use more technical means.
