mb/system76/gaze15: Add System76 Gazelle 15

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 using Intel GOP driver
- Internal microphone
- Internal speakers
- S3 suspend/resume
- Flashing with flashrom
- Booting to Ubuntu Linux 20.10 and Windows 10

Not working:

- Discrete/Hybrid graphics

This requires a new driver to work correctly, which will be added and
enabled later.
