EC 23U PCB (#20049)

* Add EC 23U PCB firmware

* Moved from data driven row/col def to config def

* Implemented proper LAYOUT_ changes

* Removed unnecessary `.h` includes

* Updated default thresholds

* Added `DISCHARGE_TIME`

Addition of a `DISCHARGE_TIME` time. This is to ensure that the ghost capacitor  that is the row strobed for the ADC read, is fully drained and doesn't carry charges that deviates the readings.

Tested on multiple hardware and confirmed working and improving the readings, both in terms of stability and consistency for baseline noise.

* Update readme.md

Added missing `cipulot/` in example commands.

* Removal of `info.json` lines as suggested

* Update to comply with `_kb` and `_user` separation

* Update rules.mk
