[Keyboard] Added IVY macropad (#6211)

* Added initial files for the Adron  3-key macro pad

* Refactor of "adron_pad" to "ivy", cleaned up the readme and removed un-needed keymap as well.

* Made suggested changes to commit for PR

* Removed unneeded define block from SUBPROJECT_rev1 as it is redundant (Thanks drashna ;) )
