Add several tests to check scroll behavior smooth/instant #13049

These tests look great overall! I know this is a really tricky spec to write good non-flaky tests and the approach taken here seems solid to me.
One request: can we give the tests more descriptive names? So scroll-behavior-default.html instead of scroll-behavior-001.html, scroll-behavior-subframe.html instead of scroll-behavior-003.html, etc.? It just makes it easier to understand a list of passing/failing tests without having to go read each one.
