renesas-ra/machine_uart: Add the UART.IRQ_RX class constant.

Browse Source 
The renesas-ra port supports calling a handler to be called on every byte
received by UART.  For consistency with other ports, the symbol IRQ_RX
is added as the trigger name.

Side change: Add the received UART data to the REPL input buffer only if it
is the REPL UART.  Otherwise, every UART would act as REPL input.
