WebKit processes should not suspend during launch and initialization
https://bugs.webkit.org/show_bug.cgi?id=277163
rdar://132590940
Reviewed by Chris Dumez.
Currently, there is a chance that WebKit processes on iOS will suspend between
launch and initialization.
This is becaues we release the launch grant in
AuxiliaryProcessProxy::didFinishLaunching, but we do not
take a foreground activity until later. For the WebContent process we do take a
foreground activity when
initializing the process, but there is a chance the WebContent process can be
suspended between the launch
and initialization events. For the Networking and GPU process, we do not take a
foreground activity during
initialization. This is addressed by capturing an activity and launch grant
when sending the message that
initializes the process, and releasing it after process initialization is
finished. This is done for all
process types.
