MouseEvent.movementX/Y - update events that set a value

[hamishwillee]

MouseEvent.movementX and MouseEvent.movementY state that the value is only set for mousemove event. In fact it is also set for pointermove on Chrome and FF, and pointerrawupdate on Chrome and FF from version 148.

This adds the clarification.

Looks fine to me from what I get from my tests and from Masayuki's descriptions. Thanks!

I initially thought that change should also be mentioned on the PointerEvent interface, but those two properties are actually part of MouseEvent and only inherited, so it is ok as is.
