Brian Osman 48c9919335 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.

Now that we're testing our TexStorage path, fix a few other problems
that showed  up:
- Command Buffer doesn't like extension formats.
- X86 PowerVR and Adreno devices don't like BGRA.
