Reason for revert: Breaking lots of bots
Original change's description:
> Add GrExternalTextureData and SkCrossContextImageData
>
> GrExternalTextureData is an API for exporting the backend-specific
> information about a texture in a type-safe way, and without pointing
> into the GrTexture. The new detachBackendTexture API lets us release
> ownership of a texture to the client.
>
> SkCrossContextImageData is the public API that lets clients upload
> textures on one thread/GrContext, then safely transfer ownership to
> another thread and GrContext for rendering.
>
> Only GL is implemented/supported right now. Vulkan support requires
> that we add thread-safe memory pools, or otherwise transfer the
> actual memory block containing the texture to the new context.
>
