Add idle texture callback mechanism.

A proc can be registered with a GrTexture. The proc will be called when
it is safe to delete the texture is "idle." Idle means it referred to
outside of GrResourceCache and that the I/O operations on the GPU are
completed (this latter part applieas to Vulkan only).

The intended use case for this is to call promise image texture release
procs once we start caching GrTextures for deinstantiated promise
images.
