Marked test expectations https://trac.webkit.org/changeset/284967/webkit

I was not able to reproduce the crash or timeout locally on iOS 15 sim using run-webkit-tests --ios-simulator --force --iterations 500 --exit-after-n-crashes-or-timeouts 1 imported/blink/compositing/video/video-controls-layer-creation-squashing.html.

Tried --test-list as well, but I couldn't reproduce.

This test continues to fail, crash, and time out periodically.

The last time this crashed or timed out was on iOS 16 on November 2, 2022. Can we consider this resolved?
