Allow to disable telemetry alarams (#4981)

* Allow to disable telemetry alarams

This mainly useful for cheap transceivers that have telemetry but no power amplifier and very limited range of often 10-20 meters. This includes fishpepper's tinyFISH FC (and its legal/illegal clones) and also Spektrum BNF models.

* Always disable a warning when RSSI Warnings are disabled

* Compile fix

* Fix typos, also mute sensor lost

Refactor the FrskyRSSIAlarm[2] into a EEPROM compatible RssiAlarm struct

* Compile fixes

* Also refactor Companion

* Cleanup unused datastruct on ARM

* Compile fix for AVR

* Change int to uin8_t for avr

* Fix strings
