Serial refactor fix (#14007)

Browse source 
* VCP - zero-init USB port in usbVcpOpen

* Serial - serialPortIdentifier_e is signed

* UART - remove unused serialPortCount

* UART - allow compiling spectrum without UART

* UART - minor improvements

closeSerialPort tests for NULL,
no other functional changes
