* UIProcess/API/mac/WKView.mm:
Don't process mouse events that would make an action menu; call super
and let AppKit take care of it. We have to duplicate the macro so that
we can avoid calling super for the internal-only methods.
Also, otherMouseMoved is simply not a thing, so remove it.

* WebView/WebHTMLView.mm:
(-[WebHTMLView otherMouseDown:]):
Don't override otherMouseDown: if the event would make an action menu.

* platform/spi/mac/NSMenuSPI.h:
Add additional NSMenu SPI.
