Allow forcing an output to be offered for DRM leasing via a new `drm-lease` config flag. This serves as a workaround for drivers (notably NVIDIA) that fail to set the `non-desktop` DRM connector property on VR headsets and similar displays.

This serves as a workaround for drivers (notably NVIDIA) that fail to set thenon-desktopDRM connector property on VR headsets and similar displays.my rtx 3090 + valve index does DRM leasing fine under sway/kwin (with worse perf/weird display flickers when the lease starts/ends), after the HMD has been configured as 'disabled' in sway/kwin.
yet another case of the nvidia drivers being of bad quality. I couldn't see an appropriate way to handle this at the Smithay layer, as I think that'd more or less require mucking with EDID data, so I think this is the cleanest way to simply mark the device as being DRM-leasable.
