[BLE] Add support for decrypting PVVX, BTHome v2 and Victron BLE frames (#2219)

* Changing WebUI to include display device name, and change it to select drop down rather than checkbox

* Fix mqttDiscovery to require WebUI and ESP32 for displayDeviceName

* Fix mqttDiscovery to require WebUI and ESP32 and ESP8266 for displayDeviceName and ForceDeviceName

* Changing WebUI to include display device name, and change it to select drop down rather than checkbox

* Fixes for WebUI and BT for supporting custom setting Display name

* Fixes for WebUI and BT for supporting custom setting Display name

* Move DISPLAY_DEVICE_NAME to User_config.h

* Update docs to include change for Display temperature

* Update docs to include change for Display temperature

* Fix minor cosmetic bug where devices were not linking in HA to the gateway using via_device as it should be the gateway mac address not name

* Add support for decrypting BTHome v2 frames

* Add support for decrypting BTHome v2 frames

* Add support for decrypting BTHome v2 frames

* BTHome fix issue with theengs-plug

* BTHome fix issue with theengs-plug

* Adding support for all BLE encrypted methods, support in UI and gatewayBT for specific MACAddress AES Keys

* Fix lint

* Fix build issue with theengs-bridge-v11 and esp32dev-all-test and revert the documentation to Units of measurement displayed

* Revert docs

* Revert displayDeviceName and Units of measurement

* Revert displayDeviceName and Units of measurement

* Revert displayDeviceName and Units of measurement

* Revert minor typo

* Revert minor typo

* Revert minor typo

* Bug in Victron as nonce should be 16 bytes

* Shortened the client side javascript for BLE key validation that is commented out due to image constrains on theengs-bridge-v11
