IMPALA-6994: Avoid reloading a table's HMS data for file-only operations.

Catalog currently loads the HMS data even, if only the file metadata load
is requested. This change detects some of those updates and tries to skip
the loading of HMS data if only the file metadata load is requested.

Testing:
  Ran the core test without failures.
