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.
