Embroider `webpackConfig` does not play well with ember-auto-import configurations

[xg-wang]

The alias for ember-auto-import no longer works when I add embroider

    autoImport: {
      alias: {
        marked: 'marked/lib/marked.esm.js',
      },
    },

I'm seeing this error when ember server --prod, notice the serve works in development env ember serve

Uncaught (in promise) Error: an unsupported module was defined, expected `define(id, deps, module)` instead got: `1` arguments to define`

Repro branch: https://github.com/xg-wang/ember-realworld/commit/2df8c725dc5915cb2cbd0c2f4f3dcb7ce603bd52#diff-e835654135548f75db36136807171b4d12d3514e043f4f80a146b88cc668fba4R11

I can workaround by passing webpack config, my question is should embroider respect alias or webpack config from e-a-i?

    packagerOptions: {
      webpackConfig: {
        resolve: {
          alias: {
            marked: path.resolve(__dirname, 'node_modules/marked/lib/marked.esm.js'),
          },
        },
      },
    },

Looks like https://github.com/embroider-build/embroider/issues/662 is about aliasing app's own js, this issue is about importing 3rd party js

Probably yes, it would be good for embroider to respect the autoImport options. It would do exactly what you're doing manually here.

Does anyone else think it would be worthwhile to add a few more details about this in the docs? I worked through a little exercise today of getting a native node module (csv-parse) to work in a default ember 4.x app and then make it work in embroider: https://github.com/jacobq/embroider-csv-parse-test

I found that (1) I basically had to move the ember-auto-import config options over to compatBuild, (2)@embroider/webpack and webpack are not the same -- though I don't really know what the differences are / when to use which except that the former did not have plugins like Webpack.ProvidePlugin, and (3) enabling staticComponents broke the build (presumably because of https://github.com/emberjs/ember-test-helpers/issues/1220).
