Closes #7320.
Rationale for this change
The Parquet format allows encrypting some or all column data while keeping footers in plaintext for compatibility with readers that don't support encryption. See spec.
Arrow-rs already supports reading plaintext footers and writing encrypted parquet files and should also support writing parquet files with plaintext footers.
What changes are included in this PR?
Are there any user-facing changes?
This now enables writing plaintext footers, while in current state attempting to write a plaintext footer would throw an error.
