Everywhere: Gently remove the ladybird android port

With Ladybird now being its own repository, there's little reason
to keep the Ladybird Android port in the SerenityOS repository.

(The Qt port is useful to be able to test changes to LibWeb in lagom
so it'll stay around. Similar for the AppKit port, since getting
Qt on macOS is a bit annoying. But if the AppKit port is too much
pain to keep working, we should toss that too.

Eventually, the lagom browser ports should move out from Ladybird/
to Meta/Lagom/Contrib, but for now it might make sense to leave them
where they are to keep cherry-picks from ladybird easier.)
