Migrate `helix` common configuration (#25433)

* Initial tidying up of top level helix/ directory

Align readme.md with template & provide more detailed PCB information
Remove unused rules.mk
Add common config.h file
Update glcdfont.c with formatting and license header

* Further migrations after PRs merged

Move shared configuration to top level info.json and config.h
More descriptive hardware compatibility

* Add changelog

* Align configuration between PCBs

- Migrate beta & pico to use RGB Matrix
- Move previously RGB Matrix-dependent OLED code in rev3/rev3.c to top level
- Remove reundant OLED code in beta/beta.c
- Remove RGBLight references

* Update changelog with RGB Matrix configuration
