Jonas Ådahl 91117bb052 monitor-manager: Don't include generated code in header file 
Meson doesn't seem to handle depending on generated headers, at least
when those headers are pulled in indirectly via another header file.

Luckily, we don't actually need to include the generated D-Bus boiler
plate in meta-monitor-manager-private.h, since the MetaMonitorManager
type no longer is based on the D-Bus service skeleton.

So, by moving the inclusion of the generated D-Bus header file into
meta-monitor-manager.c, we should hopefully get rid of the sporadic
build issues.

Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1682

/**
* SECTION:meta-monitor-manager
* @title: MetaMonitorManager
* @short_description: A manager for multiple monitors
*
* #MetaMonitorManager is an abstract class which contains methods to handle
* multiple monitors (both #MetaMonitor and #MetaLogicalMonitor) and GPU's
* (#MetaGpu). Its functions include reading and/or changing the current
* configuration and available capabiliies.
*
* The #MetaMonitorManager also provides the "org.gnome.Mutter.DisplayConfig"
* DBus service, so apps like GNOME Settings can use this functionality.
