Set the friendly Bluetooth name of the local Bluetooth adapter.

This name is visible to remote Bluetooth devices.

Valid Bluetooth names are a maximum of 248 bytes using UTF-8 encoding, although many remote devices can only display the first 40 characters, and some may be limited to just 20.

If Bluetooth state is not BluetoothAdapter.STATE_ON, this API will return false. After turning on Bluetooth, wait for BluetoothAdapter.ActionStateChanged with BluetoothAdapter.STATE_ON to get the updated value.
