7d2632c024 Implement Tx only Flush (#3433)
* add option to Flush() to only clear txQueue

Add the option to cause Flush() to just wait for tx data to clear the tx fifo and uart, leave the rx queue and rx fifo as is.

* support tx only flush()

* support txOnly for Flush()

* compatibility to Stream()

f71a4bd406 Bugfix/detect baudrate (#3188)
* Expose uartStartDetectBaudrate(uart_t *) in esp32-hal-uart.h and call it from HardwareSerial::begin() if baudrate detection is requested (by passing a baudrate of 0) to solve baudrate detection problems

* Avoid a division by zero error in uartGetBaudRate()
