[Skia] Add damage region visualization overlays
https://bugs.webkit.org/show_bug.cgi?id=315021
Reviewed by Carlos Garcia Campos.
The damage visualization overlay was specific to the TextureMapper path
(TextureMapperDamageVisualizer). Add a Skia counterpart so
WEBKIT_SHOW_DAMAGE also works when the Skia compositor is enabled.
Following the on-screen FPS counter approach, the Skia damage
visualization is drawn directly from ThreadedCompositor to the SkCanvas
rather than introducing a separate class. As with the TextureMapper
visualizer, while it is active the whole frame is invalidated each paint
so previously visualized damage rects get erased: damage is excluded
from compositing and the frame damage sent to the platform is forced to
Full.
