  [GTK][WPE] Enable testing of damaging information propagation
https://bugs.webkit.org/show_bug.cgi?id=283425

Reviewed by Carlos Garcia Campos.

This change:
- fixes damage propagation in general
- fixes damage rects for layers with custom positions and empty transforms
- fixes damage rects for viewport scale != 1
- changes the compositor's interpretation of valid-yet-empty damage so that it 
treats it as "full viewport"
to make layout tests passing with damaging enabled.
