Add interface tempAllowWhileInUsePermissionInFgs() to

ActivityManagerInternal.

So Telecomm can potentially call tempAllowWhileInUsePermissionInFgs() to
allow a FGS started for incoming call to have a while-in-use permission.
Previously tempAllowWhileInUsePermissionInFgs() is an interface in
ActivityManagerLocal, because Telecomm is in packages/services/Telecomm directory, it has
difficulty to call ActivityManagerLocal interfaces. Add
tempAllowWhileInUsePermissionInFgs() to ActivityManagerInternal is the
easiest workaround.

Bug: 270966067
Test: build and run.
