LCP: Alternative to BLUETOOTH_CONNECT to get the device name

[mickael-menu]

Until now, we requested the device name using the BluetoothManager. We need it to register an LCP license to an LSD server.

However, since Android 12 we're required to request the BLUETOOTH_CONNECT permission to the user, to get the device name. This displays this scary pop-up to the user.

I suggest instead to take an explicit device name from the app, when creating the LcpService. This way the app can handle the BLUETOOTH_CONNECT part, or use another strategy to compute a device name.

As a fallback, we can use something like that in the toolkit: "${Build.MANUFACTURER} ${Build.MODEL}", e.g. Samsung SM-N900V.
