refactor: Move drivers into properly module. * Align our driver module layout to properly match Zephyr conventions, allowing proper CMake setup to amend the library for each type of driver.

refactor(kscan): batch GPIO reads by port Changed the GPIO matrix and direct GPIO key scan drivers to do a single read per port instead of one read per pin. This is much more efficient for some types of GPIO drivers, such as I2C GPIO expanders. To accomplish this with minimal overhead, we now sort input pins by port at driver init. if we iterate through the pins in the sorted order, all pins on the same port are consecutive, so we only need to read each port once the first time we see it.

refactor(kscan): Auto enable kscan drivers The key scanning drivers are now automatically enabled when a DT node with the matching "compatible" property is present and enabled, so they no longer need to be manually set for each board.
