[FedCM] Adding preventSilentAccess in fedcm_test

Removing preventSilentAccess from individual tests and adding it
to fedcm_test itself. This reduces flakiness for tests during a
test run.

Fire error events for invalid speculation rules tags (#53822)

This CL introduces error handling for <script type=speculationrules>
with invalid ruleset-level tags. This changes the behavior: previously
we would ignore such tags and preload with the null tag. But now, we
error the entire <script type=speculationrules>, since it is better to
avoid preloading if the web developer is expecting it to get a certain
tag and we cannot fulfill that request.

This matches the spec update at
whatwg/html#11426.

Check whole complex selector for host in selector lists

The code path for featureless matching only considered the first simple
selector instead of the whole complex selector. First, the whole
compound must be considered, then if there is a combinator the selector
matching must fail since the featureless element cannot be combined with
other elements.

Re-enable flag that was set to 'test' in [1].

part 6: Rewrite `AutoInsertParagraphHandler::HandleInHeadingElement

This make AutoInsertParagraphHandler::HandleInHeadingElement:

• stop splitting the heading element if split at end
• use SplitParagraphWithTransaction if splitting the heading element

Then, this also cases the failures because not touching the invisible
<br> element in the heading element. Failing with this reason does
not make sense because not touching the heading element saves the
footprint for undo transactions. Therefore, this patch makes the tests
allow the <br>s to stay there.
