[macOS] Stop ProcessThrottler for dead processes
https://bugs.webkit.org/show_bug.cgi?id=254838
rdar://106070798
Reviewed by Chris Dumez.
We have a bug report where the ProcessThrottler continues to take
assertions on a process after it's been terminated. Usually when a
process is terminated, its corresponding WebProcessProxy and
ProcessThrottler are destroyed so this isn't an issue. However, when a
process is killed by our background CPU usage monitor the
WebProcessProxy and ProcessThrottler are not destroyed until we lazily
relaunch the process. This fix tells the ProcessThrottler that we've
disconnected from our process so that it stops trying to take process
assertions.
