Gathering resource load statistics resumes suspended WebContent processes
https://bugs.webkit.org/show_bug.cgi?id=270201
rdar://problem/123724907
Reviewed by Alex Christensen.
Right now, gathering all resource load statistics (via `
_getResourceLoadStatisticsDataSummary:`)
sends an async IPC with a completion handler to all WebContent processes. This
causes a background
activity to run which causes all suspended WebContent processes to resume just
to handle this IPC.
This process resume isn't necessary because WebProcess already flushes all
pending resource load
statistics to NetworkProcess at suspend time (see the call to
`flushResourceLoadStatistics` in
`WebContent::prepareToSuspend`). So we can avoid the process resume by just not
sending this IPC to
suspended WebContent processes.
