backends: Split out CRTC/output management to MetaGpu In order to eventually support multilpe GPUs with their own connectors, split out related meta data management (i.e. outputs, CRTCs and CRTC modes) into a new MetaGpu GObject. The Xrandr backend always assumes there is always only a single "GPU" as the GPU is abstracted by the X server; only the native backend (aside from the test backend) will eventually see more than one GPU. The Xrandr backend still moves some management to MetaGpuXrandr, in order to behave more similarly to the KMS counterparts. https://bugzilla.gnome.org/show_bug.cgi?id=785381

MetaOutputKms is changed to use MetaKmsConnector to get basic metadata, but variable metadata, those changing depending on what is connected (e.g. physical dimension, EDID, etc), are still manually retrieved by MetaOutputKms. https://gitlab.gnome.org/GNOME/mutter/issues/548 https://gitlab.gnome.org/GNOME/mutter/merge_requests/525

GBytes * meta_output_kms_read_edid (MetaOutput *output);
gpu-kms: Don't add outputs without modes There seems to be a kernel race when one disconnects an external monitor connected to a DisplayPort via a USB-C adapter. The race results in a connector being reported as connected, but without any modes supported. This had the side effect that we tried to set a preferred mode to the first listed mode, but as no modes were available, we instead tried to dereference the first element of a NULL array, causing a segmentation fault. Mitigate this by skipping adding output if no supported modes are advertised and the output doesn't support scaling, while moving the fallback path for calculating a preferred output mode to after possibly adding the common modes, to avoid the unvolentary NULL dereference. https://bugzilla.gnome.org/show_bug.cgi?id=789501
