feat!: migrate public to avm simulator

[fcarreiro]

This PR migrates the public (execution) environment to use the AVM simulator. The idea of this PR is to be as minimal as possible, as to enable easy rollbacks if needed. If things go well, there is a lot of cleanup to do afterwards, which we are tracking in this issue.

Major Changes

• PublicContext gets replaced with what was the AvmContext.
• Noir Aztec macros now always take the AVM path for public.
• Migration notes are added.

Other changes

• Delegate call tests are disabled, since the AVM doesn't support delegate calls.
• ACIR public execution tests are disabled.
• Fees were changed in bench_tx_size_fees since the cost is now different (bytecode and L2 gas changes).

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.

[dbanks12]

LGTM!

[dbanks12]

Is this TBD intended to mean "release number TBD"?

[fcarreiro]

Yes! It gets changed before the actual release, but maybe I could just do 0.42

[rahul-kothari]

can you move it into 0.41?

[rahul-kothari]

this is great! Thank you! Everything before it feels like it can be in docs and doesn't need to be in these notes. We tend to keep these notes as succinct as possible
