Make it possible to define TCXO and XTAL radio modules within one variant (#4492)

Browse Source 
* Update main.cpp

Add in TCXO_OPTIONAL variable for tcxoVoltage and a double-check for working in both modes.

* Update SX126xInterface.cpp

Make a change to the tcxoVoltage setting so that TCXO_OPTIONAL works if defined.

* Update variant.h

Added define for TCXO_OPTIONAL and the tcxoVoltage variable.

Added detail on the compatible boards.
