Fixes boards.txt entries for the atmegazero_esp32s2, and also the platform.txt  --flash_size which is not letting the board compile due to its 32MB size. (#5673)

only use ksz8081 for idf versions later than 4.3 (this fixes compile as component for idf 4.3) (#5599)

esp_eth_phy_new_ksz8081 was added in IDF after version 4.3 and generates a compilation error with IDF-4.3. This change will only use esp_eth_phy_new_ksz8081 for IDF versions after 4.3

* Create PULL_REQUEST_TEMPLATE.md

Adding first version of PULL_REQUEST_TEMPLATE.md.

The purpose of this template is to improve and simplify writing more accurate Release Notes.

* Update PULL_REQUEST_TEMPLATE.md

Fix typo.

* Update README.MD - "Type: For reference" labels link

Updating a link to issues labeled with "Type: For reference". The old one is not working due to the updates of labels in the past.

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.

Depending on `tud_cdc_tx_complete_cb` can cause in some cases the last packet to not be transmitted until more data is written and flushed. It's a rare case, but if the other end is expecting those last bytes, transmission will hang.

This PR also fixes debug output on CDC

* Add dummy test for self hosted GitHub runners

Supported devices table updated due the 2.0.0 release

Fixes: https://github.com/espressif/arduino-esp32/issues/5573

To reproduce:
1. Run any sample code that starts a BLE server, and does not call `setCallbacks`.
2. Connect to the device using the "LightBlue" app on iOS.
3. Observe crash shown in the issue linked above.

## Summary
Applies the upstream changes here: https://github.com/arduino/ArduinoCore-API/compare/3b88acac8%5E...0d83f1afc3367037dbde5323c2abd0ae1bd2c583

## Impact
Adds new String convenience methods that are now available in the mainline Arduino implementation, simplifying interoperability with C code that uses pointer+length strings rather than 0-termination. Also includes a change to avoid mutating the source string when taking a substring.

* Add support for the hardware CDC in ESP32-C3

* Adds rxBufferSize parameter to begin()

* Adds HardwareSerial::setRXBufferSize()

* Include nvs_commit() on three methods

In [Preferences.cpp](https://github.com/espressif/arduino-esp32/blob/master/libraries/Preferences/src/Preferences.cpp),  the functions:
```
Preferences::clear()
Preferences::remove()
Preferences::end()
```
should be revised to include a call to 
`nvs_commit()`
as required per 
[Non-volatile storage library](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/storage/nvs_flash.html)
when using 
```
nvs_erase_all()
nvs_erase_key()
nvs_close()
```

* Add support and example for USB HID Devices
* Add support and example for USB Vendor

## 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. 

Fix #5287  
Fix #5273 
Fix #5519 
Fix #5247 
Fix #5403
Fix #5429
Fix #5047
Fix #5463
Fix #5362 
Fix #5112  
Fix #5443 

## Impact
It solves many reported issues related to UART.
It was tested and works fine for ESP32, ESP-S2 and ESP32-C3.

## Summary
Adds support for the new ATMegaZero ESP32-S2 board. Adds the relevant section to `boards.txt` and adds the folder for the `atmegazero-esp32s2` with the proper `pins_arduino.h` to the `variants` folder.

## Impact
Allows users to compile code properly for the ATMegaZero ESP32-S2 without having to use a similar board and manually entering pin numbers.

* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result"

"The class Webserver is declared with two explicit constructors, one with signature:
WebServer::WebServer(IPAddress addr, int port)
Using this results in a server listening on the port number obtained by converting the value of the IPAddress addr argument (in host byte order) to a uint32_t and then to a uint16_t, which is manifestly not the result that would be expected.
...
As for a fix, we can assume from these results that this constructor is not being used and therefore could simply be deleted."

Reverse changes in commit bee1e7088cef913391155f096b42cd4bb89c5c6f after discussion.
Alternative fix to be done.

* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result"

This change adds support for multi-homed servers to libraries/WiFi.  It was assumed to be there already by libraries/WebServer, but was not.
This led to unexpected results when the IP address-specific constructor of class WebServer was used (see issue 5507).

This change was tested using three concurrent instances of WebServer, one bound to the WiFi station address, one bound to the WiFi soft AP address,
and one bound to INADDR_ANY.  See libraries/WebServer/examples/MultiHomedServers for the test method.

* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result" (cont.)
This fixes what I think might be the cause of CI failures on GitHub for the previous commit, namely the absence of an include file
in examples/MultiHomedServers.

* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result" (cont.)

Change port numbers in examples/MultiHomedServers per pull-request comment from me-no-dev ...
"for this test to be valid, both servers should be on the same port. That is how you can make sure that the functionality works."

This PR adds the support for the Franzininho WiFi board in CDC and MSC modes.

Thanks @chegewara

I2C Scan was failing because i2c_master_write does not accept size of 0. This change checks and skips that call if no length is provided (usually when scanning)
