esp32/uart: Add flow keyword argument to enable hardware flow control
port-esp32
This allows the hardware UART to (optionally) control the RTS and/or CTS pins.
The new "flow" keyword specifies a bitmask of FLOW_RTS, FLOW_CTS.
Without this patch, the UART driver for ESP32 ignores the RTS and CTS pins.
