[GTK][WPE] Skia Compositor: avoid copies when getting the SkImage of a tile
https://bugs.webkit.org/show_bug.cgi?id=313217
Reviewed by Nikolas Zimmermann.
SkSurface::makeImageSnapshot() does a copy-on-write, but when the
surface is wrapping an external texture, it always copies because it
doesn't know if the texture will be modified externally. We know the
texture won't change, so we can use our own cached image wihtout
copying. Also remove the now unsused code from CoordinatedBackingStoreTile
that was moved to SkiaBackingStore.
