Remove unexposed ProxyTexture, mark AnimatedTexture as deprecated

According to reduz:

> [AnimatedTexture] should be removed together with ProxyTexture, its just
> not efficient at all in Vulkan and causes invalidation of all descriptor
> sets depending on it
> it was needed mostly for animated tilemaps, but nowadays there is not a lot
> of reason for it

Marking AnimatedTexture as deprecated accordingly, until we reach consensus
for removing it completely.
