[addon-dev] Allow TS files in publicEntrypoints / appReexports

[josemarluedke]

For addons authoring their code in TS (or soon gjs/gts), currently is not possible to use @embroider/addon-dev's publicEntrypoints or appReexports methods.

We cannot use them because the dist files will end up with the same extension as the input.

In glimmer-apollo, I ended up doing a simple replace of .ts with .js.

It turns out this isn't needed - stay tuned!

I think the solution in #1099 is solid~ish, but I need to figure out a peerDep issue -- #1062
I think I'm getting two copies of xstate in the consuming app, and it's only revealing itself because of component-manager's reliance on object identity. 🤔

@josemarluedke - Can you put up a separate (smaller) PR from #1099 that ensures that the output path is .js similar to what you did here (though with more robust extension replacement support probably)?

[josemarluedke]

@rwjblue Can definitely do it. Should extension replacement support the following mapping?

• ts -> js
• gts -> js
• gjs -> js
• hbs -> js

[rwjblue]

yep! but I think we already have hbs -> js done right?
