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

This reverts commit 0c78238e2991c95b6fb3c945d4ad2b5d941ae21b.

Reason for revert: <INSERT REASONING HERE>

Original change's description:

> 
> This reverts commit cd2c3f9055452d413d6be7ea6dc63fd1922fe994.
> 
> Reason for revert: Looks to be causing angle failures on initial clear test

> Original change's description:

> > 
> > If we get a non-mipped texture for a draw that wants to be use mip map filter, we

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