IMPALA-15149: Add type-aware Trino result verification

Collect output metadata through PREPARE and DESCRIBE OUTPUT using the
existing Trino CLI. Normalize Trino types to the query test vocabulary,
verify optional TYPES sections, and use actual types for value comparisons
even when TYPES is absent.

Add focused coverage for metadata parsing, normalization, empty results,
type mismatches, update mode, floating-point comparison, and non-finite
FLOAT/DOUBLE values. Document the new authoring contract and exercise it in
an interop test.
