8222: Move and link top sites feature RFC. r=jonalmeida a=pocmo



8226: Closes #8209 - Use new onTouchEventForResult GV api r=pocmo a=Mugurell

Changes:
- previously NestedGV#onTouchEvent event would call onTouchEventForResult where
we would make possible the integration of GV in CoordinatorLayout.
Since NestedGV#onTouchEvent does not anymore call onTouchEventForResult I've
moved all code in onTouchEvent and then call onTouchEventForResult only for
ACTION_DOWN events as snorp recommended.
- we now must wait for onTouchEventForResult#GeckoResult<Int> and only then
call startNestedScroll(..) since otherwise when executing that method in
BrowserToolbarBottomBehavior we would return false since the MotionEvent is
at that time unhandled.
- only dispatch startNestedScroll and dispatchNestedPreScroll if GV returned
INPUT_RESULT_HANDLED.

In testing I saw most of the times GeckoResult resolves in < 5ms with bigger
timeouts showing a logarithmic growth. As such I think the change should be
imperceptible to users.

- Ignored "ClickableViewAccessibility" since NestedGeckoView is not intented
to be clickable, but rather the elements from the webpage displayed.

In testing I saw most of the times GeckoResult resolves in < 5ms with bigger
timeouts showing a logarithmic growth. As such I think the change should be

Issue #8121: Replace MigrationStore with MigrationContext and prevent usage outside of a Middleware.

* Before executing the reducer chain we now verify that we are on the store thread and throw if we are on a different thread.
* MigrationContext now provides a store property that returns the underlying Store instance. This can be used to pass it to
  other components and threads that are not part of the Middleware.
* Fixed existing Middleware implementations to use the MiddlewareContext or pass the actual Store instance around.

8233: Close #8232: Remove firebase-core dependency from lib-push-firebase r=pocmo a=jonalmeida

For Cloud Messaging, we no longer need `firebase-core` as a dependency. This removes unneeded services that can run on the device.

8236: For #7832: Support concept-menu in custom tabs r=jonalmeida a=NotWoods

I'm thinking that we can adjust the menu down the line so that it just responds to browser state updates instead of having a couple of components change the menu themselves. This is part of that work for custom tabs. No changelog yet as this is just groundwork for later.
