Convert the RxCy macros to constsexprs

Move `KEY_INDEX` here, and turn it into a `constexpr` function, `keyIndex`, and
convert the `RxCy` macros to constexpr values instead.

/* To be used by the hardware implementations, `keyIndex` tells us the index of

* fewer elements than the declared array size, the remaining elements will be
* zero. We can use this to avoid having to explicitly add a sentinel in
