Set user restriction when mic/camera toggles are used

The user restriction will result in the app op returning MODE_IGNORED so
the providers know that they shouldn't deliver mic/camera data.

The camera service needs to check the state of the toggle directly on
app op change so it knows that the ignore was a result of the toggle.

TODO: don't allow this restriction to be bypassed
