Parquet schema file type coercion functionality is not applied on all fields in nested schemas, only on the top-level fields

[adragomir]

Describe the bug

• ATM, the Parquet file schema type coercion applies view transforms for example only on top-level fields, but not on nested fields.
• For some Parquet schemas, where we request a view transform for a nested field, this translated to an unmodified schema passed to the reader. Then, when we try to apply predicates on the actual data, the actual predicate execution needs a cast, because the schemas are different.

The issue is visible in integration for example with delta-rs.

1. Delta-rs - when schema_force_view_types is true, applies this flag recursively on nested schemas.
2. The recursively-modified schema is passed through the layers to datafusion, until apply_file_schema_type_coercions
3. But, apply_file_schema_type_coercions does not take into account modifications on the nested fields, onlt on the top-level fields.
4. So, the Parquet is opened without having view types on nested fields
5. Then, when we try for example to apply predicates - which ARE using view types, because that is what delta-rs knows it has - datafusion needs to cast the data to have view types, resulting in longer predicate evaluation.
