[Private Click Measurement] Fix PCM attribution reports not sent after system
sleep/wake cycles
https://bugs.webkit.org/show_bug.cgi?id=305659
rdar://167733375
Reviewed by Alex Christensen and Matthew Finkel.
PCM attribution reports were not being sent when the device went to sleep
before the scheduled fire time. The issue is that a timer is not reliably
fired after we wake from sleep, even if it should’ve fired in the past.
This prevents sending overdue attribution reports.
This fix adds SystemWillSleep/SystemDidWake IPC messages to NetworkProcess
and updates WebProcessPool to send these notifications to NetworkProcess
during system sleep/wake events. On wake, NetworkProcess checks for overdue
PCM attributions and restarts timers.
