Autogenerated with:
cp dom/.clang-format widget/ && mach format widget/**.{cpp,h,mm}
Manual changes:
* Had to add a manual override in nsWaylandDisplay.h /
DMABufFormats.cpp to include mozwayland before protocols.
* Missing includes in nsWindowWayland/X11.h / nsDragService.
* nsFilePicker missed an nsWindow forward declaration.
* Various overrides in widget/windows because windows headers are order
dependent.
