[HWCDC] Improve HW CDC Implementation (#5643)

Browse Source 
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.
