Return old and new ChangeInfos in get-meta-diff

Currently, users of the get-meta-diff REST API endpoint get information
about removed and added fields between two states of a change. A use
case is to then retrieve the ChangeInfo from the REST API with another
request to know fields such as branch, project, and Change-Id. This
information is easily returned by the get-meta-diff endpoint, reducing
the number of queries made to Gerrit. This is impactful when
get-meta-diff users are subscribing to the Gerrit Cloud PubSub. This can
reduce the number of API calls that directly result from a PubSub
message by half.

Always return the two states of the change in the get-meta-diff
response.
