Terry Kim c27a616450 [SPARK-30612][SQL] Resolve qualified column name with v2 tables ... ### What changes were proposed in this pull request? This PR fixes the issue where queries with qualified columns like `SELECT t.a FROM t` would fail to resolve for v2 tables. This PR would allow qualified column names in query as following: ```SQL SELECT testcat.ns1.ns2.tbl.foo FROM testcat.ns1.ns2.tbl SELECT ns1.ns2.tbl.foo FROM testcat.ns1.ns2.tbl SELECT ns2.tbl.foo FROM testcat.ns1.ns2.tbl SELECT tbl.foo FROM testcat.ns1.ns2.tbl ``` ### Why are the changes needed? This is a bug because you cannot qualify column names in queries. ### Does this PR introduce any user-facing change? Yes, now users can qualify column names for v2 tables. ### How was this patch tested? Added new tests. Closes #27391 from imback82/qualified_col.
