[macOS] When a background WebProcess uses too much CPU in the background,
suspend it
https://bugs.webkit.org/show_bug.cgi?id=256607
Reviewed by Geoffrey Garen.
When a background WebProcess uses too much CPU in the background, suspend it
when process suspension is enabled. We would previously terminate the process
which is not as user-friendly and unnecessary when we can suspend to process to
stop it from using CPU.
