LibWebView: Add common source loop source for deferred_invoke() on macOS

Browse Source 
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.
