Consider change ETag computations from plugins when computing ETag for actions

Change I358e3d4fb added an extension point that allows plugins to
contribute to the ETag computation of changes. One case where plugins
need to contribute to the ETag computation is if they implement a
SubmitRule which is based on plugin data, because only then it is
guaranteed that callers always see current submittable information in
ChangeInfo.

In the case where a plugin implements a SubmitRule it is also important
to include the change ETag computations from plugins when the ETag for
revision actions is computed because the revision actions decide whether
the 'Submit' button should be shown. If change ETag computations from
plugins are not considered when the ETag for the revision actions is
computed it can happen that the submittable information in ChangeInfo
disagrees with the presence/absense of the 'Submit' button.
