esp32/machine_uart: Improve sendbreak so it doesn't reconfig the UART.
Currently, `UART.sendbreak()` on esp32 will reconfigure the UART to a
slower baudrate and send out a null byte, to synthesise a break condition.
That's not great because it changes the baudrate of the RX path as well,
which could miss incoming bytes while sending the break.
This commit changes the sendbreak implementation to just reconfigure the TX
pin as GPIO in output mode, and hold the pin low for the required duration.
