This change is to address API review, add respective
@IntDef for network policy API.
Typedef cannot be exposed as SystemApi so add
ConnectivityAnnotations class and add an annotation library
so that it can be used in module and platform.
Bug: 183972925
Test: m, build doc target framework-doc-stubs_annotations.zip
and check the APIs have an attribute IntDef annotation

The service-connectivity sources should be in
packages/modules/Connectivity. Move them to
frameworks/base/packages/Connectivity, so that the whole directory can
be moved to the dedicated packages/modules/Connectivity git project.
