[GTK][WPE] Add single-entry GPU atlas cache to SkiaPaintingEngine
https://bugs.webkit.org/show_bug.cgi?id=309005
Reviewed by Carlos Garcia Campos.
When the image set is unchanged between frames reuse the GPU atlas from
the previous frame GPU instead of allocating new textures, uploading pixels
and re-creating the atlas. The cache is cleared when atlas layouts change
or disappear -- ensure the memory usage cannot grow unbounded.
Covered by existing tests.
