feat: support "umd" format

[fi3ework]

Summary

TODO:

umdModuleName lacks some advanced features:

1. non string type
2. auto transform to camel case

We might implement them after understand why they're supported in https://modernjs.dev/module-tools/api/config/build-config.html#umdglobals.

---

update:

1. Don't need to support auto transform to camel case, it was a limitation when implement with swc.
2. non string type might support it.

I think I need to split the UMD config from the current example as it will mix the benchmarks all together.
