mesa: Prefer non-swizzled formats for most sized internalformats
These formats can be cast to others (with different component types or
sizes) via ARB_texture_view or ARB_shader_image_load_store. We want
them to be laid out consistently so that we can just reinterpret the
memory with a different format.
In V1, this was done conditionally on a 'prefer_no_swizzle' flag which
was set in TexStorage/TextureView paths, but we need the same behavior
for ARB_shader_image_load_store (which also works with images created
via TexImage, so we don't want it to be conditional.
