Oriol Brufau d5c82150e0 layout: Add testing API for counting restyled and rebuilt fragments (#42817)
Now `ServoTestUtils.forceLayout()` will provide the number of fragments
that have been restyled and rebuilt. This will be useful to test that
incremental layout works well.

Testing: Adds a test using this new API
