vrend: Correctly handle FakeMSAA textures

Browse Source 
If nr_samples is 1 we allocate textures as MULTISAMPLE, so we also need to handle
the textures in later use as a multisample texture. In addition, on GLES blits to
a multisample texture are not allowed as target, and we must use the GL blit
fallback for all texture types.

v2: Correct more checks including the one in check_resource_valid (Gurchetan)
v3: Also update the tests to use only 0 for no samples and >= 1 for samples
