Handle Authorization for 'select <expr>' hive queries in SQL Standard Authorization

Hive internally rewrites this 'select <expression>' query into 'select <expression> from _dummy_database._dummy_table', where these dummy db and table are temp entities for the current query.
The SQL Standard Authorization need to handle these special objects.

Typing "select reverse("123");" in beeline,will get this error :

Error: Error while compiling statement: FAILED: HiveAuthzPluginException Error getting object from metastore for Object [type=TABLE_OR_VIEW, name=_dummy_database._dummy_table] (state=42000,code=40000)
