Field Metadata Lost on UNION #12735

Describe the bug

During upgrade of DataFusion in InfluxDB @itsjunetime found that somewhere Field level metadata (aka Field::with_metadata is being lost during DataFusion logical planning

This manifests itself as an error during the physical planning

Internal Error: Physical input schema should be the same as the one converted from logical input schema

To Reproduce

Run this query in metadata.slt

# Regression test: missing field metadata, from the NULL field on the left side of the union
query ITT
(SELECT id, NULL::string as name, l_name FROM "table_with_metadata")
  UNION
(SELECT id, name, NULL::string as l_name FROM "table_with_metadata")
ORDER BY id, name, l_name;

Expected behavior

No error during physical planning
