Commit 84fc54f6bf introduced the use of RG
formats with a swizzle as backing store for guest requested LA formats.
This works for many cases (e.g. blitting), but unfortunately it can't be
used when rendering with blending to an LA target. Since GL doesn't
support texture write swizzles the swizzle needs to happen in the
fragment shader and that's too early for proper blending.
We can safely revert the offending commit since the tests fixed by it
have since been fixed by other commits (e.g., "vrend: Nop sends to
backing iovs for readonly textures v2") in a different way. The one
side effect of reverting is that, depending on the GL version, a less
efficient path may be taken in the guest Mesa when mipmapping LA formats
since they may not be considered color-renderable anymore.

Update the GL blit code to support blitting for multisample textures,
for both normalized and integer color formats.
The minimum GLSL ES version in the shaders is also raised to 3.1, since
GLSL ES 3.0 doesn't support multisample textures.

This is even conflicted in reference documents. Just handle
