zephyr: use interrupt based RX buffering
Poll-based RX was technically incorrect since Zephyr was setting up
the UART to FIFO mode (instead of byte mode). This change replaces
polling the RX UART with interrupt based callbacks. When calling
uart_shell_stop(), the ISR will be replaced and will instead queue
items to a ring buffer which can be read from uart_getc() (it can
also be cleared via the uart_clear_input() function).
