Make SPI frequency and TOPHONE queue size configurable on Native (#4369)

* Make SPI frequency configurable on Native

* Make the tophone queue size configurable for Portduino

* The modified SPISettings must be configured in setup(), after config.yaml is processed

* make MeshService a pointer, so we can configure MAX_RX_TOPHONE at run time

* Got a little over excited with refactoring

* Silence a warning
