Removed a bunch of whitelist entries that were no longer needed, mostly
due to completed servicification migrations.  Some usage was
no-longer-needed includes that I removed, and all of UrlInfo appeared
to be no longer used or present in build files so I removed the whole
class and tests.

Some usage of MDnsClient was just accessing the Get...Endpoint()
methods that could easily be moved to net/dns/public and thus no longer
require whitelisting.

Ensured all remaining whitelist entries were commented with why usage
is appropriate or with a TODO and bug for anything still requiring
servicification migration.
