This is useful going forward in particular because there will
be a default forbidden capability for LOCAL_NETWORKS. This
means it will be useful to be able to remove it.

It is also generally useful and we have been wanting to open
this API to the public, so this is a good opportunity to do so.

Test: new tests for NetworkRequest
      NetworkCapabilitiesTest already has tests because it
      already was @SystemApi

Add aconfig_declarations so that platform code can use this flag.
Following CLs(aosp/2606670) use this flag to sync the mainline behavior
change and platform behavior change.
Having merged-in to avoid being merged to udc-mainline-prod where
aconfig soong targets are not supported

This CL does not have Merged-In since all the branches should have the
aconfig file so that adding flags to the file does not have conflicts.
Following CL adds aconfig_declarations to Android.bp only on branches
where aconfig soong targets are supported

The kernel is actually not consistent in whether uids & gids
are signed or unsigned, and neither is our Java code, which
also commonly uses just 'int' for uid.  In practice values
greater or equal to 2**31 often don't quite work right.
For example icmp sockets are enabled via a sysctl that
takes a minimum and maximum gid - and these are signed int32s.

These are allocated in order by the kernel, if we go
over 2 billion, we've got other problems... besides
U32 to S32 conversion will work just fine anyway.

Surprisingly it appears no further fixups are required
to make this compile, due to other places already being 'int's.

Need to share struct CookieTagMap{Key, Value} with:
service/src/com/android/server/connectivity/ClatCoordinator.java
service-t/src/com/android/server/net/NetworkStatsService.java
tests/unit/java/com/android/server/connectivity/ClatCoordinatorTest.java
tests/unit/java/com/android/server/net/NetworkStatsServiceTest.java

These files only have different package name as expected.

$ diff common/src/com/android/net/module/util/bpf/CookieTagMapKey.java service-t/src/com/android/server/net/CookieTagMapKey.java
