Gergely Fürnstáhl 8d034a2f7c IMPALA-11034: Resolve schema of old data files in migrated Iceberg tables
When external tables are converted to Iceberg, the data files remain
intact, thus missing field IDs. Previously, Impala used name based
column resolution in this case.

Added a feature to traverse through the data files before column
resolution and assign field IDs the same way as iceberg would, to be
able to use field ID based column resolutions.

Testing:

Default resolution method was changed to field id for migrated tables,
existing tests use that from now.

Added new tests to cover edge cases with complex types and schema
evolution.
