SX126x/8x: Also use PREAMBLE_DETECTED IRQ flag for actively receiving check (#2349)

Browse Source 
* Use startReceive() instead of startReceiveDutyCycleAuto()

* Add preamble detected IRQ

* Escape from 'freeze' state when packet should have been received

* Use RADIOLIB_GODMODE for access to clearIrqStatus

* SX126x: Better handling of false preamble detections

* SX128x: Add preamble IRQ and false detection handling to active receiving check

* Remove unnecessary function declaration
