Allow deletion of some (as opposed to all) textures on the impl thread.
Enable removing uploads to evicted textures from texture upload queues. Track whether not a CCPrioritizedTexture::Backing has been evicted in the structure itself. Purge texture upload queues of evicted backings instead of clearing the entire queue.
Added CCTextureUpdateControllerTest.ClearUploadsToEvictedResources to test the new eviction logic.
