DPL Analysis: Improve arrow schema serialization

[aalkin]

• Support fixed- and variable-size columns when converting to arrow::Field
• Add the table schema to its relevant InputSpec to support creating empty tables directly
• Add the schemas of tables used as a sources for a generated table in its InputSpec metadata
• Add serialization/deserialization for the list-type fields
• Add test for the realistic data model table schemas
