This change updates MacOS event loop implementation to allow notifiers
to be unregistered from threads other than the one they were created on.
Upcoming IPC changes will move transport socket reading into separate
thread and depend on this behavior.
Previously, `EventLoopImplementationMacOS` didn't process
`deferred_invoke()` callbacks during window resizing because they were
scheduled in the "default" run-loop mode, which isn't serviced while the
run loop is in "Event Tracking" mode.
Commit 3bbe1b0c changed socket notifiers to schedule in
`kCFRunLoopCommonModes`, which kept IPC reads responsive during resizing
(we process IPC messages in the notifier's read hook). This change does
the same for `deferred_invoke()`: it installs a `CFRunLoopSource` in
`kCFRunLoopCommonModes` and signals it whenever a deferred callback is
enqueued.
This method was removed in e015a43b51
However, it was not exactly *unused* as the commit message would say.
This method was the only thing that allowed spin_until to exit when
the event loop was cancelled. This happens normally when IPC connections
are closed, but also when the process is killed.
The logic to properly handle process exit from event loop spins needs to
actually notify the caller that their goal condition was not met though.
That will be handled in a later commit.
We currently compile the Qt event loop files multiple times, for every
target which wants to use them. This patch moves these to LibWebView as
a central location to avoid this.
