Description
### Describe the enhancement requested
https://github.com/apache/arrow/pull/49667 adds `create_encryption_properties` and `create_decryption_properties` functions for generating file encryption and decryption properties by directly specifying a footer key, but these only support uniform encryption, where all columns are encrypted with the footer key.
These methods should be extended to support per-column encryption keys.
