Implements UART SerialHardware Refactoring on top of IDF (#5549)

Browse Source 
## 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.
