nrf: Consolidate all stdio functions.
Consolidate CDC, UART and NUS stdio interfaces into the one handler. Allows any/all of them to be enabled separately. Updates UART REPL to use similar define to other platforms: `MICROPY_HW_ENABLE_UART_REPL`. USB now uses the shared/tinyusb CDC implementation. Signed-off-by: Andrew Leech <andrew@alelec.net>
