A helper class to *read* java BpfMaps. This is designed to
provide direct bpf access in the caller process through
ConnectivityManager APIs.

The change also removes any statical link to
net-utils-device-common-struct from service-connectivity.
This is because net-utils-device-common-struct is already
included in framework-connectivity. Including it again in
service-connectivity would create a r8 build fail by circular
dependency.

The TTL check and removal of expired services is currently only
performed when a mDNS query is sent. This can result in expired
services remaining in the cache if no queries are sent. To
address this, the remaining TTL will be checked when retrieving
services from the MdnsServiceCache. Add a new flag to enable
the expired services removal feature. This feature will be
implemented in subsequent changes.

I0afdda023208c3f8620cb5b89add66448af596d7 added some assertions
to ensure NetworkAgentInfo can only be accessed from the handler
thread. This is good to eliminate any potential concurrent
accessing problem. Howver, dumpsys runs on binder thread, this
change breaks dumpsys functionality.

Thus, this change:
  1. Copy Handler#runWithScissors() and related class
     locally since they are @hide methods.
  2. Run doDump on the handler thread and waits for return.

This is catched by errorprone where global variables accessing
is not protected by the declared lock, which could lead to a
potiential race problem where these variables are changed but
cannot be seen for the invocation.

This is also safe since:
  1. The method called inside mDefaultNetworks is already holding
     the same lock.
  2. Multiple global variables are protected by this synchronized
     block.
