device/trivial: reorder defines in "nm-device.c"

Reorder code to be like in other source files:
- first includes and generic defines
- then various helper structs
- then GObject related declarations, with first signal and property
  enums, then the private data, then the G_DEFINE_TYPE() itself.
- finally, forward declarations for functions.

(cherry picked from commit f97d8b86fb)
