Support for Android private / signature permissions

[Qwin]

Why it is needed?

Currently the Permission type does not support private/signature permissions like com.google.android.gms.permission.CAR_VENDOR_EXTENSION, I would like to ask to support those permissions as well or at least just allow freeform as an overload.

Possible implementation

requestMultiple([PERMISSIONS.ANDROID.BLUETOOTH_CONNECT, PERMISSIONS.ANDROID.BLUETOOTH_SCAN, "com.google.android.gms.permission.CAR_VENDOR_EXTENSION"])

just a note but the above does not work sadly I get unavailable and never get a prompt when I forcibly type it as Permission, while using AndroidPermissions (default react-native library) does work with the above code for the private permission

UPDATE:

looking at the code a bit closer I think the issue is with this method here not accounting for privledged / signature permissions:

UPDATE 2

So figured out the issue it seems that https://developer.android.com/reference/android/Manifest.permission doesnt have the CAR_VENDOR_EXTENSION permission in it due to it being a system level permission only given out to some companies. Because of that I propose the following solution:

requestMultiple(permission, { skipManifestCheck: true }), that way you can skip the check above and avoid it from being unavailable. 

UPDATE 3

looking at the permission itself based on this post, it seems to be a dangerous permission:

This is fixed in v5.0.0. As it's not exposed, you need to cast it:

requestMultiple("com.google.android.gms.permission.CAR_VENDOR_EXTENSION" as Permission)
