  [GTK][WPE][Skia] Refactor threaded CPU rendering code into its own class SkiaThreadedPaintingPool
https://bugs.webkit.org/show_bug.cgi?id=280589

Reviewed by Carlos Garcia Campos.

This is a first step towards threaded GPU painting -- refactor the
threaded CPU rendering code (including display list recording tools)
into its own class: SkiaThreadedPaintingPool. Leave the GPU rendering
code as-is.

Covered by existing tests.
