[AppKit Gestures] Gesture recognizer driven inputs can stop working after web
content process crash
https://bugs.webkit.org/show_bug.cgi?id=313322
rdar://175599268
Reviewed by Richard Robinson.
There is a bunch of local state tracked within the UI process bound
AppKit gesture controller that we fail to clear when the web content
process terminates, which would leave the controller in a stale state.
For example, if the web content process crashed during an on-going drag
gesture, it would permanently suppress mouse tracking.
To remedy this, we add a reset method that clears all process-dependent
state and have it called from WebViewImpl::handleProcessSwapOrExit().
