[FR]: app foreground system permission

### Description

We found that GoogleDataTransport will initiate network status monitoring when the app enters the foreground, which will trigger the system permission pop-up window. This conflicts with the demand of our app. Could you add a control switch so that the app can actively turn on this function

### API Proposal

_No response_

### Firebase Product(s)

Functions

Start by locating the GoogleDataTransport code path that begins network status monitoring when the app enters the foreground. Determine where an app-controlled switch would be exposed and verify the permission prompt behavior with Firebase Functions; done means the app can opt in to monitoring without automatic foreground activation.
