feat: support `[wasm_modules]`

See original GitHub issue

We currently support .wasm modules, so in module-format workers, you can import wasm and instantiate it (like, import something from './something.wasm';).

We should also support “legacy” style wasm, so anything passed to [wasm_modules] in wrangler.toml is available as a binding in service-worker format workers. (I was surprised to learn of this configuration field today. It makes sense that this exists and works, I was just surprised it doesn’t appear to be documented at https://developers.cloudflare.com/workers/)

I’m not sure, I used the output of the workers-rs base project https://github.com/cloudflare/workers-rs to generate that example folder

Cloudflare workers does it a little differently at the moment, it’s imported as WebAssembly.Module that you can instantiate. Example here https://github.com/cloudflare/wrangler2/blob/main/examples/wasm-app/worker/module/export_wasm.js Here’s an older blogpost with some details https://blog.cloudflare.com/webassembly-on-cloudflare-workers/
