Add debug controller The debug controller can optionally, when passing --debug-control, enable manipulating debug state, so far enabling/disabling HDR, via D-Bus. It's always created, in order to have a place to store debug state and emit signals etc when it changes, but so far, it doesn't have its own state it tracks, it just mirrors that of the monitor manager.
