Merge 126540 - [chromium] Fix lost context when textures are evicted

Merge 126540 - [chromium] Fix lost context when textures are evicted
https://bugs.webkit.org/show_bug.cgi?id=94892

Reviewed by James Robinson.

After eviction, the CCPrioritizedTextureManager is in a limbo state
where all its resources are invalid. If we try to release them we will
double-destroy them.

New test: CCLayerTreeHostTestLostContextAfterEvictTextures.
