chore: add simple bb installer script

[TomAFrench]

As of #6320, we're now expecting users to maintain an installation of bb and update its version as required.

To help with this, this PR adds an ultra dumb bbup script fashioned from noirup which only allows installing released versions of bb. This means that users can run bbup -v 0.38.0 to install 0.38.0 of bb.

Happy to make any changes as requested.

[TomAFrench]

I think it's worth progressing with this in the short term pending the client/server model switch and have bb.js install the binary. We can delete this after that work is complete.

Benchmark results

No base data found for comparison.

Detailed 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.

[guipublic]

The script seems to rely on some nargo env variables such as $NOIRUP_REPO, $NARGO_BIN_DIR. I wonder if it should check for a nargo installation first?

[TomAFrench]

Actually, that code referencing NOIRUP_ env vars should be removed entirely as it's not relevant. Thanks for pointing that out.

[Savio-Sou]

For posterity's additional context, bbup is currently recommended in the Noir docs' installation section: https://noir-lang.org/docs/dev/getting_started/barretenberg/

If anyone reading is has an updated recommended way to install bb, please update the Noir docs and give the Noir team a heads up. Thanks!
