Require mips to be allocated at texture creation time and disable late allocations.

If we get a non-mipped texture for a draw that wants to be use mip map filter, we
will copy the texture into a new mipped texture.

Clean up of unused code in the GPU backends for reallocating for mips will be done
in a follow up CL.
