mainboard/hp: Add ProBook 450 G3

Linux support is pretty good, as there are only minor issues and some
are not related to firmware. On the other hand, Windows support is
experimental and is currently not recommended to use.

See `Documentation/mainboard/hp/probook_450_g3.md` for details about
tested features and known issues.
