mb/system76/rpl: Add Galago Pro 7 as a variant

The Galago Pro 7 (galp7) is a Raptor Lake-H board.

Tested with a custom TianoCore UefiPayloadPkg.

Working:

- PS/2 keyboard
- I2C HID touchpad
- Both DIMM slots (with NMSO480E82-3200EA00)
- M.2 NVMe SSD
- All USB ports
- SD card reader
- Webcam
- Ethernet
- WiFi/Bluetooth
- Integrated graphics using Intel GOP driver
- Backlight controls on Windows 10 and Linux 6.2
- HDMI output
- DisplayPort output over USB-C
- Internal microphone
- Internal speakers
- Combined headphone + mic 3.5mm audio
- S3 suspend/resume
- Booting Pop!_OS Linux 22.04 with kernel 6.2.7

Not working:

- Detection of devices in TBT slot on boot
