[Keyboard] Kinesis + Pro Micro (#9944)
* [Keyboard] Kinesis + Pro Micro init

- docs for DIY
- custom matrix = lite
- a near-factory dvorak mapping
- optimized debouncing for lower latency

* chore: reformatting

* chore: update doc

* chore: cleanups according to PR feedback

* chore: PR feedback

* fix: compile error

* chore: add include

* fix: LEDs hanging after USB disconnect

* chore: enable QMK goodies by default

* chore: use semantic write pin
