Improve bundle size by replacing detective-typescript (#10825)

* replace `detective-typescript` with our own implementation

We are not parsing the code but just trying to pluck out the
dependencies used via `import` and `require`.

* drop `detective-typescript`

* return a `Set` instead of an `Array`

* resolve rebuilds, but log errors in case they occur

This won't be the prettiest if it happens, but at least we are not
swallowing errors which should make bugs be easier to discover.

See previous commit for an example... 😅
