Added passive mode for Sen5x sensor (required for Ike@ Vindstyrka) (#19388)

Browse Source 
* Added a passive mode in sen5x sensor for parasitic installations. This skips reset & initialization of sensor on startup and reduces the polling to every 10 seconds to not interfere with and confuse the other I2C master on the bus, e.g. Ike* Vindstyrka.

* Removed obsolete updateCount. Cleanup.
