Android 12 'nearby devices' permission support

[thide11]

In recent years, a global trend is to increase user privacy

And with the advancement of Android, it was no different here

In versions lower than Android 12, to use Bluetooth, you needed to request the user's location, a bold permission and for users it doesn't make sense to ask for location to use Bluetooth

Thanks to android 12 a new permission can be asked from users: "nearby devices", this pull request uses the new android manifest permissions so you don't need to request location from users on more modern devices

Before:	After:

Several pull requests have already been made in this project with the same functionality, but I decided to create my own for the following reasons:

• They ask on old devices for location permission to turn Bluetooth on and off, there is no need to ask if you don't go beyond that, in more modern versions, then yes, 'nearby devices' permission is needed to turn Bluetooth on/off
• The error message if it does not have permission is generic or unchanged, in this pull request it warns that the 'nearby devices' permission is missing if it is a new device and 'localization' if it is an older device
• Some created very long ifs or duplicated calls to methods that you don't need, such as ActivityCompat.requestPermissions

Hope this contribution helps!
