Move wifi services out of system_server into a separate APK/process. Changes: a) Created sepolicy for the new wifi apk. b) The new APK will run with network_stack uid (eventually will be moved to the same process). Used 'audit2allow' tool to gather list of permissions required. Note: The existing wifi related permissions in system_server is left behind to allow the module to be loaded into system_server or network_stack process depending on device configuration. Bug: 113174748 Test: Device boots up and able to make wifi connection. Test: Tested hotspot functionality. Test: Ran WifiManagerTest & WifiSoftApTest ACTS tests locally. Test: Will send for wifi regression tests. Change-Id: Id19643a235bf0c28238f2729926b893ac2025b97 (cherry-picked from c7aa90091e6bec70a31a643cc4519a9a86fb0b38)
