Cleanup framework-connectivity to reduce its memory and storage usage:
- Build libframework-connectivity-jni using standard C and removing
dependencies on libc++. This saves about 100kB of storage (40+60kB
on the 32+64 bit variants).
- Remove dependency on protobuffer libraries, as their usage has been
removed. This saves about 15kB of storage.
From local measurements, the reduced code size also improves memory
usage.
This also removes a jarjar workaround for net-utils-device-common, as
the library is no longer used either.

NetworkUtils can just use the NDK to achieve the same.
Also make sure network handles can have the local nameservers flag, for
the JNI API, and create/parse them accordingly in Network.

Currently, queryUserAccess talks to netd via FwmarkServer.
Doing this from the module would require exposing queryUserAccess
as an NDK API or reimplementing FwmarkClient.
Because queryUserAccess really only uses information that comes
from ConnectivityService/PermissionMonitor anyway, just use that
information without calling to net.

The API is the getter couterpart for setprocnetwork.
Use it in NetworkUtils so that the NDK API can be the source of truth
for the process network.

Use the jniThrowErrnoException that is available in JNIHelp, instead of
reimplementing in NetworkUtils.

Keep the utilities included via a library, but move them out of
core/jni, and prepare a library to package them together with
framework-connectivity.
Also remove unnecessary dependencies in framework-connectivity.
