input: add some initial keyboard matrix library stubs We currently have three keyboard scanning drivers in the code base (npcx, it8xxx2 and mchp_xec, last two yet to be converted to input). These have been largely copy pasted from each other and share a lot of the same structure and code. This PR lays a foundation to start decoupling feature from those drivers into a common code base, and it is heavily inspired by the current regulator common data/config one. Feature wise this only moves the thread struct, stack and initialization to the common code and declares the thread callback as the only API, but the intent is to move as much code as possible in there an only abstract device specific callbacks in the api structures.

Enable library used for keyboard matrix drivers.

help
Size of the stack used for the keyboard matrix thread.
input: kbd_matrix: make the thread priority configurable Add a config entry for the keyboard matrix thread priority. This changes the current default, but that was pretty much an arbitrary numbe anyay and the exact one should be picked the application so it should be alright to do so.

help
Priority level of the keyboard matrix thread.
input: gpio_kbd_matrix: add 16 bit rows support Add a Kconfig option to extend the row type to 16 bits, allowing the library to handle a 16 row matrix. Signed-off-by: Fabio Baltieri <fabiobaltieri@google.com>

config INPUT_KBD_MATRIX_16_BIT_ROW
bool "16 bit row size support"
help
Use a 16 bit type for the internal structure, allow using a matrix
with up to 16 rows if the driver supports it.
input: kbd_matrix: add actual key mask runtime control Add an option to enable a input_kbd_matrix_actual_key_mask_set API to enable or disable keys dynamically in the mask. This can be useful if the exact key mask is determined in runtime and the device is using a single firmware for multiple matrix configurations.

input: kbd_matrix: add an kbd_matrix_state shell command Add a "input kbd_matrix_state" shell command. This prints the state of a keyboard matrix in a much more compact representation than the normal input event dump, but also keeps track of any key seen during the execution and reports that on the "off" command. The output can be used to help setting the actual-key-mask property. Signed-off-by: Fabio Baltieri <fabiobaltieri@google.com>
