* AVRO-3814: Fix schema resolution for records in union types

The logic for validation records in Value::validate_internal() would be
too strict when resolving union types containing a record. This could
lead to a situation where schema resolution would fail because the
correct schema to use for a union type could not be identified.

This commit fixes this by passing a boolean `schema_resolution` to
`Value::validate_internal()` which governs whether schema_resolution
rules should be applied.
