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

This reverts commit cd2c3f9055452d413d6be7ea6dc63fd1922fe994.

Reason for revert: Looks to be causing angle failures on initial clear test

Original change's description:
> 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.
>
