Add new permission for on device screen recorder

We want to exempt on device screen recorder from blacking
out senstive content. we want to block sensitive content
projection over the network i.e. when screen is shared.

Our expectation is that most OEM would be using sys ui
recorder, but some of them may provide their own recorder.
