[GTK][WPE] Add Sysprof marks for mouse events
https://bugs.webkit.org/show_bug.cgi?id=308737
Reviewed by Adrian Perez de Castro.
Mouse event processing in the UI process begins in
`WebPageProxy::handleMouseEvent()` and ends in
`WebPageProxy::mouseEventHandlingCompleted()`.
To enable tracking of the time spent handling these events,
corresponding `WTFBeginSignpost()`/`WTFEndSignpost()` calls have been
added to these methods.
To distinguish between multiple mouse events, a unique identifier is now
assigned to each `WebEvent` and included in the signpost name.
Additionally, signposts are emitted for Wayland `motion` and `button`
events in `WPEWaylandSeat` to mark the start of event processing.
