Make proving/verifying work in SnarkyJS with kimchi about o1js

[mitschabaude]

Proving works 🎉 I'll devote another morning to see if I can get pickles verifying to work in JS as well, because that would be a nice sanity check. (Verifying already works for non-recursive proofs, so we shouldn't be too far off)

[mitschabaude]

Verify works as well now 🎉

The only remaining TODO is to fix the regressions that come up when merging develop in the branch where it works (MinaProtocol/mina#10267)

As snarkyjs is being merged in a version where everything works and is tested in CI, this can be closed :)

Matt fixed the proving bug, and proving works for the low-level Circuit interface now.

However, this isn't quite done, because recursive pickles proofs don't work yet (which are the ones we need for snapps). The issue is that they get returned as a Deferred, but deferred's never actually finish in JS, because there is no "scheduler" for them. I'm trying to solve that now.

Pushed a branch which seems to solve the problem described above: https://github.com/MinaProtocol/mina/tree/feature/snarkyjs-pickles-proof
This makes a fairly wide-reaching change to the code base, and still has to be consolidated with develop

However, a new issue turned up - a missing implementation of Kimchi.Oracles.create in the Wasm version

Set up this PR to fix the async prover issue: MinaProtocol/mina#10454

[mitschabaude]

Multiple Wasm / bindings issues are fixed, and the proof seems to work - there's only an issue with asyncness left, where the proof is computed, but the promise that should hold it resolves early with a value of undefined
