Subject: [PATCH] backend/drm: save current refresh rate
wlr_output.refresh is populated by core wlr_output, and thus will
be zero for a custom mode with an unset refresh rate.
Save the refresh rate from the drmModeModeInfo in wlr_drm_connector
instead.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3791
