fix: modules not built sequentially

[njlynch]

For Go, JS, and Python, the OneByOneBuilder is used to build the modules
sequentially. The modules are first sorted topologically, then passed into the
builder to build one at a time. However, the package builds are kicked off
asynchronously, leading to parallel builds and potential build issues when a
local package depends on another.

I guess we could do a reduce to build a single promise chain here but the for/of loop feels easier to read and fits better with our code style, lint ignores and all. Alternative would be something like:

await this.modules.reduce((previous, mod) => {
  return previous.then(() => this.options.codeOnly
    ? this.generateModuleCode(module, this.options)
    : this.buildModule(module, this.options)
  );
}, Promise.resolve())

We could have the best of both worlds: chain dependent tasks together and run independent ones in parallel. But of course, there is more effort involved in making this work and may not be worth it.
