chore: Remove Ultra Grumpkin flavor

[codygunton]

The Grumpkin flavor of Ultra Honk doesn't actually work over Grumpkin, or use IPA, so I get rid of it since it has no reason to exist.

Benchmark results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.

Values are compared against data from master at commit b36fdc48 and shown if the difference exceeds 1%.

LGTM, seems like you got rid of it all.
