shell: enable UART backend without interrupts

Browse source 
Currently shell UART backend is interrupt driven if UART driver
is interrupt driven. That can be limitation if one instance
wants to use interrupts but shell UART should not.

Added option to shell uart to be able to control use of
interrupts. By default interrupts are enabled if driver
supports it.
