Add notes about variants

Our variant IDs are nondescript inconsistent, and unintuitive.
Add some notes to the Makefiles to more quickly identify them.
Some extra notes:

- gaze17-3060 doesn't exist
  - It was copied from gaze16 variants
- lemp13 only had a 14" option with different keyboard layouts
  - I've chosen to label the original layout "cursed"
- Some models are a refresh without any significant changes
  - darp10/darp11, oryp6/oryp7
  - Potential to merge them at some point?
