…ger` for consistency with native interface (#3891)

# Description

Merging the work done here:

AztecProtocol/aztec-packages#3696
#3781
#3760

Plus some extras to make the API nicer.

## Problem

Closes(?) #3695

## Summary

Makes noir_wasm easier to work with, including dependency resolution and
bundling. This package can be used from both node and the browser with
identical API leveraging a virtual filesystem.

Uses webpack for bundling, which is done in two steps: 

1) rust -> wasm (cjs/esm)
2) TS + wasm (cjs/esm) -> universal package for web

Tests have been migrated to mocha and playwright.

## Additional Context

~~I really want to test it
[here](https://github.com/signorecello/noir-playground) before merging,
but it's in a state in which it can be reviewed before we commit to an
API.~~
Done: signorecello/noir-playground#32

Even though the initial memFS-backed FileManager developed by @alexghr
is still here, it is not used for the web version due to import
problems. The way it works now, webpack uses `memfs` directly it to
alias the node `fs` module (which seems to be its intended use case) and
allows us to use the nodejs `fs` API everywhere.

## Documentation

Documentation is required for usage, but should basically be:

```typescript

// Node.js

import { compile, createFileManager } from '@noir-lang/noir_wasm'; // Rename!!

const fm = createFileManager(myProjectPath);
const myCompiledCode = await compile(fm);
```

```typescript

// Browser

import { compile, createFileManager } from '@noir-lang/noir_wasm'; // Rename!!

const fm = createFileManager('/');
for (const path of files) {
  await fm.writeFile(path, await getFileAsStream(path));
}
const myCompiledCode = await compile(fm);
```

Check one:
- [ ] No documentation needed.
- [ ] Documentation included in this PR.
- [ ] **[Exceptional Case]** Documentation to be submitted in a separate
PR.

# PR Checklist

- [x] I have tested the changes locally.
- [x] I have formatted the changes with [Prettier](https://prettier.io/)
and/or `cargo fmt` on default settings.
