Moved the keyboard portion to #26100 per the contrib guide

chibios-21.11.x has support now. This is ready for merge

[zvecr]

Outside of chibios-contrib needing to be updated separately to pull in a later version, I don't think we would consider the port of high enough quality at the moment for us to add support.

I will update this comment when I have a little more time, but this includes:

• QMK specific variables that have bleed into the chibios-contrib port
• The usb driver looks particularly bad
  • Required use of NO_USB_STARTUP_CHECK
  • Coupled to expectations on QMKs endpoint use

This PR, as well as the dependent keyboard PR, also has quite a number of issues that would block it from being merged. These include not following the existing conventions and abstractions set up in the code base.

Marking as draft so that it does not accidentally get merged.

Thanks once you update I'll look. Ignore the keyboard part for now its state is due to my splitting it out from this, I plan to revamp it once this is merged as its the easy part.

Id defo appreciate a suggestion on naming convention for kb as its a generic multi brand.
