Rework the terminal input selection into an explicit three-way Kconfig
choice so the format each keyboard delivers is picked up front:
- On-screen keyboard (touch) - default, unchanged behaviour.
- Matrix / upper-half keyboard - reads struct keyboard_event_s events
(for example the M5Stack Cardputer matrix on /dev/kbd0).
- USB HID keyboard - reads a byte stream (for example /dev/kbda with
CONFIG_USBHOST_HIDKBD).
The physical-keyboard variant now polls the device non-blocking from the
LVGL thread (no dedicated task), mirroring the touch variant. The USB
path decodes the stream with the keyboard codec, so with a driver built
for CONFIG_HIDKBD_ENCODED the Up/Down cursor keys scroll the terminal;
a plain-ASCII stream still works as ordinary key presses.

Select how the terminal receives keystrokes. Only one input source

is built at a time. The physical-keyboard options differ in the data

the keyboard device delivers on read(), so pick the one that matches

the hardware.

Input comes from an on-screen LVGL keyboard operated by touch; a

|
command line is typed and submitted with Enter. This is the default
|

and matches the original behaviour.

Physical keyboard registered through the INPUT_KEYBOARD upper half,

USB HID keyboard (for example on /dev/kbda with CONFIG_USBHOST_HIDKBD).
|

read() returns a byte stream that is decoded with the keyboard codec:

normal keys go to the shell and, when the driver is built with
