input: split npcx generic keyboard code into input_kbd_matrix.c Move all the generic code from the Nuvoton NPCX keyboard scanning driver into input_kbd_matrix.c. While doing that convert few configs into devicetree properties and tweak few other things to enable the generic code to support multiple instances. This is limited to 8 rows for now, and that's fine for all the current in-tree drivers, the limit could be removed down the road but this should be fine for now, added few generic build checks to make sure a driver does not go over the limit, as well and some more implementation specific checks.

input: add some initial keyboard matrix library stubs We currently have three keyboard scanning drivers in the code base (npcx, it8xxx2 and mchp_xec, last two yet to be converted to input). These have been largely copy pasted from each other and share a lot of the same structure and code. This PR lays a foundation to start decoupling feature from those drivers into a common code base, and it is heavily inspired by the current regulator common data/config one. Feature wise this only moves the thread struct, stack and initialization to the common code and declares the thread callback as the only API, but the intent is to move as much code as possible in there an only abstract device specific callbacks in the api structures.
