Add a wlr_output_set_subpixel()

drmModeConnector.subpixel doesn't seem to detect subpixel order on many displays (especially laptops). Allow subpixel order to be manually set.

The corresponding PR for sway adds a subpixel output option: https://github.com/swaywm/sway/pull/3645

Once both are merged, https://github.com/swaywm/sway/issues/3163 will be fixed.
