WIP: Publish types in build package

[jelhan]

This changes the publish setup to build the types with Glint in declarations directory and publish them.

The published package still contains TypeScript files. They are not transpiled to JavaScript before publishing. But they weren't before. So that's not a regression.

Not a TypeScript expert here. Mainly copied the setup from Ember Bootstrap.

This is still not fully working. The structure of declarations folder is not as expected. It is (simplified):

• declarations/
  • addon/
    • template-registry.d.ts
    • helpers/
      • t.d.ts
  • addon-test-support/
    • set-locale.d.ts
  • tests/
    • test-helper.d.ts

But I think it should be

• declarations/
  • template-registry.d.ts
  • helpers/
    • t.d.ts
  • test-support/
    • set-locale.d.ts

The wrong structure breaks type lookup in consuming applications.

I'm not sure why it's wrong. The TypeScript configuration looks the same as for Ember Bootstrap. And in Ember Bootstrap it is working fine.

Keeping it in WIP until we figured that one out.

This is likely wrong causing the issues. See https://github.com/ember-cli/ember-cli/blob/fa8599058bde3c745a2b1156076955ca3543c857/blueprints/addon/index.js#L101-L107

@jelhan I used ember-cli to check how it now creates a v1 addon with TypeScript. You can check the commits in #1835.

When I ran npm publish --dry-run in ember-intl, I saw that the unpacked size will increase due to the addition of declaration files. So I wonder if there's really a benefit of removing ember-cli-typescript in a v1 addon, when this could potentially introduce regressions. What do you think?

Will close this in favor of #1885.
