[GTK][WPE] Move per-buffer frame-damage bookkeeping into
SwapChainDamageTracker
https://bugs.webkit.org/show_bug.cgi?id=317290
Reviewed by Carlos Garcia Campos.
Prepare for further enhancments when using the damage information to
restrict the area needed for composition in the Skia compositor: Extract
AcceleratedSurface's per-buffer frame-damage accounting - the frame
damage, its rectangle threshold, and the per-target accumulation done by
renderTargetDamage() - into a dedicated SwapChainDamageTracker, and replace
SwapChain::addDamage() with a forEachTarget() helper the tracker uses to
propagate damage across targets.
The public API was left untouched, the new SwapChainDamageTracker is
left as internal detail to AcceleratedSurface, for better encapsulation.
