Support Avro format in filesystem destination

### Feature description

It would be great to have Avro format support to dump data as avro files to filesystem or cloud storage.

### Are you a dlt user?

I'd consider using dlt, but it's lacking a feature I need.

### Use case

Data Lake that uses Avro format by default to store raw data.

### Proposed solution

Implement format support as one of the options of `filesystem` destination similar to JSONL, Parquet and CSV.
