Revert "Expand texturability testing to cover mip-mapped textures, and fix iOS"

This reverts commit 9f6f41b01bdc8144808e78128676087bfb310a27.

Reason for revert: Command Buffer and ANGLE failures.

Original change's description:
> Expand texturability testing to cover mip-mapped textures, and fix iOS
> 
> Don't allow creation of mip-mapped textures when caps says we don't
> support mip-mapping.
> 
> Skip testing of mip-mapped resources in the resource size test,
> when creation will fail.
> 
> For iOS devices with ES2, the APPLE BGRA8888 extension is more
> trouble than it's worth. Even though it lets the internal and
> external formats not match, it appears that the driver remembers
> the first external format, so subsequent attempts to upload with
> the other swizzle will fail. Up until now, creation of these
> textures was failing anyway, so now just make it more explicit
> that we don't support BGRA in this situation.
