Implement invert for HardwareSerial (#6816)

Browse Source 
* Simple i/f to turn on inverted logic on UART0.

* Refactor invert from HardwareSerial to uart

* Final refactoring of invert bits into config bitmap.

* Overload instead of default arg for subclassing.

* Prevent unwanted effects if setting invert on other than UART0 - only that has these flags defined and documented.
