[Keyboard] Refactor handwired/splittest to support multiple boards (#6373)

* Refactor splittest to support multiple dev boards

* Refactor splittest to support multiple dev boards - revert change to number of RGB led

* Refactor splittest to support multiple dev boards - update docs

* Refactor splittest to support multiple dev boards - correct docs
