Subject: [PATCH] Bug 2080242 - Include WidgetUtilsGtk.h for Wayland builds in
 nsAppShell.cpp. r=stransky,gtk-reviewers,emilio

nsAppShell::IsSessionRestoreSupported() calls IsGnomeDesktopEnvironment()
under MOZ_WAYLAND, but WidgetUtilsGtk.h, which declares it, was included
under MOZ_ENABLE_DBUS only. Builds with dbus disabled fail to compile.

Include the header when either is enabled: the dbus code uses
IsCancelledGError() and the Wayland code uses IsGnomeDesktopEnvironment().
