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
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.

Thanks!
* The board.txt has been updated. Added variant folder.
Necessary additions for deneyapMiniKart were made in board.txt. Added pins_arduino to variant folder. deneyapMiniKart information has been added.
* Added variant files and added text in board.txt

* Add initial support for USB MSC
* Add Firmware Upload/Download With MSC
Current running firmware is available as file inside the MSC Disk. To update the firmware on the ESP, just copy a regular firmware bin into the drive
* Support overwriting of the firmware file
Overwriting a file is done totally differently on MacOS, Windows and Linux. This change supports it on all of them.
* Allow CDC, FirmwareMSC and DFU to be enabled on boot
* Add example ESP32-S2 USB-ONLY board
* Various device code optimizations
Added `end()` methods to MSC classes
Made begin() methods safe to be called multiple times
Optimized CDC class
* Fix CDC Connect/Disconnect detection in Arduino IDE on Windows
* Rework cdc_write
* Update ESP32-S2 board configs
* Fix compile archive arguments for the new toolchain
* Add menu to S2 for picking through which port to upload
Internal USB CDC requires to reset and wait for the new port (because persistence is not yet stable)
* USB CDC should also be started in main
* Fix URL and USB version for WebUSB
* Update vendor callback API
* Update CDC::write to use TX_DONE semaphore
* Update USB_Serial example
Add support for the Trueverit Universal IoT Driver MK II (https://www.trueverit.com)
The board will be released on market using electronic distributors soon, as the other one board added via #5219
This new board (referred as MK II) has onboard Texas Instruments DP83848 Eth PHY chip.
* Removed ProS2 and added TinyS2 to boards.txt
* Fixed incorrect NUM_OUTPUT_PINS - should be 47 not 45
This is why my APA doesn't work on my FeatherS2 as it usess IO45 and the check is for < not <=
* TinyS2 from boards.txt got stomped with old proS2 stuff (no idea why), so adding it back in.
done on behalf of @ladyada, this PR does:
Add Adafruit FunHouse and upcoming Adafruit Feather Esp32s2
Update Adafruit magtag and metro esp32s2 to have tinyuf2 as factory app
Also modify platform.txt as discussed in adafruit#2 + adafruit#3 + adafruit#4 to add support for
Board/variant partition.csv, bootloader.bin ( priority is user sketch > variant > build.parition/boot )
upload.extra_flags to optionally flash tinyuf2 as factory application
Remove duplicated parameter in running python script in linux and windows
Please review and let me know if you want any changes.
Notes: tinyuf2 is a uf2 bootloader for multiple platforms. For esp32s2, it is an factory app to perform uf2 firmware update.
Add the Wemos Lolin32 Lite (no longer being produced same as Lolin32) and
the TTGO T7 v1.3 and v1.4 boards (status unknown). All three are rather
generic ESP32 boards the main difference being pin layouts.
