Peter Johanson 9782518397 feature(drivers): Option for read wait on matrix.
* Add a new Kconfig option, `ZMK_KSCAN_MATRIX_WAIT_BEFORE_INPUTS`
  to delay reading inputs after setting an output active.

When iterating over each output to drive it active, read inputs, then set
inactive again, some boards may take time for output to propagate to the
inputs. In that scenario, set this value to a positive value to configure
the number of ticks to wait after setting an output active before reading
the inputs for their active state.

help
When iterating over each output to drive it active, read inputs, then set
inactive again, some boards may take time for the previous output to
"settle" before reading inputs for the next active output column. In that
scenario, set this value to a positive value to configure the number of
ticks to wait after reading each column of keys.

If this is -1, the debounce time is controlled by the debounce-press-ms
