Make IncludedInDetail a static class of IncludedInResolver

IncludedInDetail is only used by the IncludedIn change REST API
endpoint and in the tests for the IncludedInResolver.

Make it a static class of IncludedInResolver and rename it to
Result which is a bit shorter.

Remove the now unused IncludedInDetail class from gerrit-common.
