Added constructor to Grid for compatibility with 8.0.7 (#9206) (#9209)

Constructor Grid(Class, DataCommunicator) was added to 8.0.7 and ported
to master to maintain backward compatibility.

Also fixed javadocs of constructors Grid(DataCommunicator) and
Grid(PropertySet, DataCommunicator) to reflect that constructors were
backported to 8.0.x and available since 8.0.7
