e3054ef5901. Remove 'federated exports' system, which was named entrypoint exports
for every module inside the plugin. Replace it with a single import of
the target plugin's 'compatModules', and then update call sites to do a
'just in time' lookup of the module and export. This is implemented in a
new `babel-resolve-plugin-imports` plugin
2. Update theme & plugin build systems to produce a list of external
plugins which are imported. For plugins, it's stored in the manifest.
For themes, it's stored in a new column of the javascript_caches table.
3. Refactor theme extra_js loading to use a more structured data model,
and move the HTML generation to the erb template
4. Update core importmap to identify any missing plugin dependencies and
add a fake placeholder module for them. This allows optional imports to
exist without causing a boot error. The imported values will resolve to
'null'.
5. Update core plugins to remove use of `optionalRequire`, and replace
it with regular imports, and a `with { discourseImport: "optional" }`
suffix. This is functionally equivalent to optionalRequire, but without
leaning on the legacy `loader.js` system of core
6. Add support for `with { discourseImport: "optional" }` for
plugins/themes importing core modules. This is useful when a
theme/plugin needs to target multiple versions of Discourse core.
