formats: Disable ASTC on GL hosts
For GL hosts CopyImageSubData and TextureView are not defined when ASTC textures are involved, and the copy fallback currently doesn't handle these formats correctly. Since Gallium can handles ASTC texures transparetly in the guest, host support is not really required to be able to use it.
