Subject: [PATCH] Add NETWORK_STACK permission

Add a new permission that only allows other system services to call
networking related methods.  This permission is intended to prevent
other apps from calling these methods that might leave networking
services in intermediate states.

Bug: 36538042
Test: build, run wifi unit tests, boots, wifi connects
