zink: modifier fixup
This adds a new util_format function in order to address regressions from #3654 (closed). We still don't apply the modifiers, but we can continue creating single-fd resources that use them and not regress functionality.
fixes:
spec@egl_nok_texture_from_pixmap@basic
spec@egl 1.4@eglcreatepbuffersurface and then glclear
spec@egl 1.4@largest possible eglcreatepbuffersurface and then glclear
