espressif/esp-idf / components/driver/include/driver/uart.h defines the API:
esp_err_t uart_set_pin(uart_port_t uart_num, int tx_io_num, int rx_io_num, int **rts_io_num**, int **cts_io_num**);
uartSetPins uses that api but alls it with swapped CTS/RTS pins as its API uses a different pin ordering:
uart_set_pin(uart->num, txPin, rxPin, **ctsPin**, **rtsPin**);
This fixes the wrong order in the function uartSetPins
Summary
Added compiler.warning_flags to all chips in platform.txt to reflect users setting of warning level output during compilation (set up in Arduino IDE preferences)
Impact
When a warning is set to none the compilation will no longer display warnings

Solves issue #6118
* Adds HardwareSerial::setTxBufferSize()
* uartBegin def fix
* checks TXBufferSize as defined in IDF
Makes sure that the buffer size will not cause a reset to the board.
* Removes double value in Rx/Tx Buffer Size
Keeps Rx/Tx buffer size as set, not doubling it. It makes the process more clear.

HardwareSerial flush() was returning before all data was sent out through serial port.
This is a problem to some RS485 libraries that depend on it to signaling.
This PR solves the issue by forcing it to block flush() until all data is sent.
This pull request contains a few fixes and improvements to the HWCDC implementation.
- Rework `HWCDC::write()` to accept unlimited data
- Add Semaphore to guard the TX Ring Buffer
- Add events support
- Remove unnecessary 1200bps touch for flashing over HWCDC
- Fix `HardwareSerial::setDebugOutput()` not resetting `putc` if the port is already selected, causing debug output to also show on HWCDC even when not selected.
## Summary
This PR is a complete reffactoring of UART Serial Hardware and respective HAL in order to use IDF instead of current Register manipulation approach.
It implements Arduino SerialEvent functionality.

## Impact
It solves many reported issues related to UART.
It was tested and works fine for ESP32, ESP-S2 and ESP32-C3.
Fixes#5112
Call to pinMatrixInDetach() was changed from version 1.0.6 in version 2.0.0 injecting a bug as seen in cores/esp32/esp32-hal-uart.c

* `ledcWriteTone()` added a `apbcallback()` evertime the tone value was non zero.
* `addApbChangeCallback()` did not detect duplicate callbacks.
* changed the apbcallback list to a double link to support roll forward, roll back execution. This made the sequences of clock change callback start with the newest registered -> to oldest on the `before` then oldest -> newest after the clock change. This made the UART debug log output have minimal gibberish during the clock change.
* change how the UART callback handled the MUTEX because if any `apbchangeCallback()` executed a `log_x()` a deadlock would occur.
This fixes#3555
* add option to Flush() to only clear txQueue
