[WPEPlatform] Page scrolls at double speed when scrolling with two fingers
https://bugs.webkit.org/show_bug.cgi?id=308643
Reviewed by Carlos Garcia Campos.
When scrolling begins with one finger and a second finger is placed on
the screen and both fingers move together, the page scrolls at twice the
expected speed.
`WPEGestureDetector` only tracks the first touch sequence and ignores
events from other sequences. However, `handleGesture()` did not check
whether the event was actually processed and always proceeded to emit a
scroll event based on the current gesture state. As a result, touch move
events from the second finger triggered a second scroll event, doubling
the scroll speed.
Fixed by making `wpe_gesture_controller_handle_event()` return a boolean
indicating whether the event was consumed.
