Eager Per Row Debouncing added (added to Ergodox) (#5498) 

* Implemented Eager Per Row debouncing algorithm.

Good for when fingers can only press one row at a time (e.g. when keyboard is wired so that "rows" are vertical)

* Added documentation for eager_pr

* Ported ergodox_ez to eager_pr debouncing.

* Removed check for changes in matrix_scan.

* Added further clarification in docs.

* Accidental merge with ergodox_ez

* Small cleanup in eager_pr

* Forgot to debounce_init - this would probably cause seg-faults.

You can either use your own code, by including your own debounce.c, or switch to another included one. You can either use your own code, by including your own debounce.c, or switch to another included one.
Included debounce methods are: Included debounce methods are:
* eager_pk - debouncing per key. On any state change, response is immediate, followed by ```DEBOUNCE_DELAY``` millseconds of no further input for that key * eager_pr - debouncing per row. On any state change, response is immediate, followed by locking the row ```DEBOUNCE_DELAY``` milliseconds of no further input for that row.
For use in keyboards where refreshing ```NUM_KEYS``` 8-bit counters is computationally expensive / low scan rate, and fingers usually only hit one row at a time. This could be
appropriate for the ErgoDox models; the matrix is rotated 90°, and hence its "rows" are really columns, and each finger only hits a single "row" at a time in normal use.
* eager_pk - debouncing per key. On any state change, response is immediate, followed by ```DEBOUNCE_DELAY``` milliseconds of no further input for that key
* sym_g - debouncing per keyboard. On any state change, a global timer is set. When ```DEBOUNCE_DELAY``` milliseconds of no changes has occured, all input changes are pushed. * sym_g - debouncing per keyboard. On any state change, a global timer is set.
