Brent Schroeter 890ef58052 devtools: Use active pipeline and script channel in inspector actors (#43153 )

The `InspectorActor` and its children now query the
`BrowsingContextActor` for the active pipeline ID and script sender
instead of storing their own copies, which become outdated on
navigation. Previously, the inspector remained permanently stuck to the
pipeline that was active upon launch. Now, connecting a fresh devtools
client session after navigation allows inspection of each
`BrowsingContext`'s active DOM.

Navigation within a continuous remote debugging session still breaks the
Firefox inspector panel. This is due to multiple compatibility issues
with the protocol implementation, which will be addressed in separate
PRs.

This PR does not touch `TimelineActor` or `FramerateActor`. These are
theoretically affected by the same issue as the `InspectorActor`, but in
practice neither is ever instantiated. It seems both have been
effectively unreachable code since 1aab10f2 and will require more
extensive work and testing that is beyond the scope of this change.

Testing: Updates to the `WalkerActor` and `BrowsingContextActor` are
unit tested via the new `test_walker_observes_new_dom_after_nav` case in
`devtools_tests.py`. There are no existing unit tests to reference for
the highlighter and style actors; these have been tested manually but
this PR does not introduce further automated tests. This PR also
improves handling of `tabNavigated` messages to simplify the unit test
written for 4c69d85.
