Move config_apf* resources to NetworkStack

The resources are only read by NetworkStack through their respective
ApfCapabilities SystemApi methods.
As the resources are being migrated out of frameworks/base resources
anyway, move them directly to NetworkStack instead of moving them to
ServiceConnectivityResources.

Also test that the framework resources are not overlaid or modified.
This should avoid OEM integration errors where the overlays are kept as
in R, without overlaying the resource in the NetworkStack package.

Test: atest CtsNetTestCases
BYPASS_INCLUSIVE_LANGUAGE_REASON=Need to mention legacy APIs
