Modify new BT config using MQTT (#1259)

* Move BTConfig_default to ZgatewayBT.ino as BTConfig_init()

* Remove unused function declaration & typo

* Move bleconnect outside of ifdef ESP32

* Add new parameters to json payload on MQTTtoBT/config
And move them to function BTConfig_fromJson()

new parameters: [presenceEnable, presenceTopic, presenceUseBeaconUuid, extDecoderEnable,
extDecoderTopic, filterConnectable, pubKnownServiceData,
pubUnknownServiceData, pubKnownManufData, pubUnknownManufData,
pubServiceDataUUID, pubBeaconUuidForTopic]

* Add ignoreWBlist as new configuration parameter

* Keep hasspresence keyword (do not use presenceEnable)

* Documentation

* Typos & Optimizations arround RemoveJsonPropertyIf

* Template for BT config update

* Ensure BTConfig.minRssi sign does not matter

* Report configuration change on topic /commands/BTtoMQTT/config

# Conflicts:
#	main/ZgatewayBT.ino

* Add BT config bool commands (init, load, erase & save) to persist config parameters

* Documentation

* Fix pre-compilation issue

* Fix Code Format

* Use Preference only for ESP32

* Update Doc
