[Backport] CVE-2022-4438: Use after free in Blink Frames
Cherry-pick of patch originally reviewed on
https://chromium-review.googlesource.com/c/chromium/src/+/4055626:
Make WidgetBase::BeginMainFrame resilient to disposed 'this'
This patch makes sure that WidgetBase::BeginMainFrame can finish
execution even if processing the RAF-throttled handlers
(DispatchRafAlignedInput) destroys 'this' instance.
(cherry picked from commit af6e22c14bec7ad64115b24ece6d423f144214ca)
