Export custom TypeScript worker variables

A custom TypeScript worker factory function gets passed
`TypeScriptWorker`, `ts`, and `libFileMap`. It also exports `create`
using ESM. However, this can’t be used, because the custom worker
factory is only called if a custom worker path is defined.

Exposing these members, means a worker can be defined using ESM.
