Avoid 8-bit timer overflows in debounce algorithms (#12240) * Add fast_timer_t that is 16-bit or 32-bit based on architecture A 16-bit timer will overflow sooner but be faster to compare on AVR. * Avoid 8-bit timer overflows in debounce algorithms Count down remaining elapsed time instead of trying to do 8-bit timer comparisons. Add a "none" implementation that is automatically used if DEBOUNCE is 0 otherwise it will break the _pk/_pr count down. * Avoid unnecessary polling of the entire matrix in sym_eager_pk The matrix only needs to be updated when a debounce timer expires. * Avoid unnecessary polling of the entire matrix in sym_eager_pr The matrix only needs to be updated when a debounce timer expires. The use of the "needed_update" variable is trying to do what "matrix_need_update" was added to fix but didn't work because it only applied when all keys finished debouncing. * Fix sym_defer_g timing inconsistency compared to other debounce algorithms DEBOUNCE=5 should process the key after 5ms, not 6ms * Add debounce tests
