mb/system76/oryp5: Add System76 Oryx Pro 5

Tested with TianoCore payload (UefiPayloadPkg).

Working:

- PS/2 keyboard, touchpad
- Both DIMM slots
- Both NVMe ports
- SATA port
- All USB ports
- Webcam
- Ethernet
- Integrated graphics
- Internal microphone
- S3 suspend/resume
- Flashing with flashrom
- Booting to Ubuntu Linux and Windows

Not working:

- Discrete/Hybrid graphics
- Internal speakers

These two require new drivers to work correctly, which will be added and
enabled later.
