tty-handler: Use raw byte handling for terminal

When opening the tty for local UART mirroring, disable various special
processing of terminal input and output like flow control, line edit
(canonical) mode, character translation, special characters, etc.

This forwards all terminal input to the VUART and allow the host OS to
perform any necessary processing.
