FEATURE: Plugin support for transpiling regular .js files (#9398)

Browse Source 
This adds support for a new piece of metadata to your plugin.rb
files. If you add:

```
transpile_js: true
```

Then Discourse will support transpilation of assets in your
`assets/javascripts` directory. Previously they had to be named
`.js.es6` but now regular `.js` will work.

Note this is opt-in because some plugins currently have `.js` files in
app/assets that are not meant to be transpiled.

Going forward all plugins should migrate to this setting as they are
comfortable able to do so.
