nshlib, graphics/microwindows: require the keyboard byte stream

Browse source 
Both read a keyboard as a stream of characters:  NSH uses a USB HID
keyboard for stdin, and the raw mode of the Microwindows keyboard driver
decodes the stream with the codec.  That stream now comes from
INPUT_KEYBOARD_BYTESTREAM rather than from the USB HID driver itself.

Say so, so that Kconfig refuses a combination that cannot work instead of
letting the application read events and treat them as text.  No in-tree
configuration selects either option.
