Reviewed by Alan Baradlay.

Add content-visibility perf tests based on chromium display_locking perf tests.
The tested scenarios are:
- a container has width toggled between predefined widths on each animation frame
- In -scolling.html additionally tests the container outside the viewport is scrolled into the viewport

The tests are repeated for both content-visibility:hidden and auto, and for containers as div, grid or flexbox.
