[Keyboard] Add new keyboard: Omnikeyish - A replacement PCB for the Northgate Omnikey family (#6167)

* Add omnikeyish keyboard support.

* remove out of date comment

* PCB Rev 1.1 moved Row5's pin to E6, because the teensy++ hangs an onboard LED off D6.

* Move string.h include to .c file

* Add pcb kicad link.

* Add info.json

* Move macro programming to numlock's keyposition, the most useless key on the post model M layout. Force numlock enabled on host at init time, so you're not stuck without a numpad (hopefully)

* Make the macro blink function toggle LEDs from their previous state.

* Use incorrect but code style compliant opening curly bracing style.

* Make PCB rev 1.1 the default Omnikeyish config, as the author has the only rev 1.0 boards that'll ever be.

* Fix silly spelling error in 3 defines

* First set of review changes.

* Layout macro and keymap defined using it.

* Layout macros for the northgate factory plates.

* minor rearrangements

* ALL the layouts.

* Forgot ultra-t in info.json
