ARROW-8151: [Dataset][Benchmarking] benchmark S3File performance

This does some basic refactoring of the S3 filesystem test to share some code, but I'd appreciate any feedback on how to better organize things.

This currently has 4 sets of benchmarks:
- A test of reading an entire file of various sizes from S3
- A test of reading sequential small chunks of those files
- A test of using coalescing to read those sequential small chunks
- A test of reading a Parquet file

Closes #6675 from lidavidm/arrow-8151-s3-bench
