Add JSDoc typeof support via JSDoc plugin

[kungfooman]

We had many issues around typeof and at some point simply settled on... the wrong type.

This caused a trail of ts-ignore comments, but I never realized that JSDoc has a plugin for exactly this issue: jsdoc-typeof-plugin

So this PR simply integrates that plugin and since now we have a correct type, we can let go of maaany ts-ignore comments.

This is cool. Thanks!

Yes, fantastic find!
I think there are few more as well in those app create options .. for example lightmapper and batcher should be typeof, as we pass in type, and not the instance.

PR's with more lines removed than added - best PR's 🙏

Yep, absolutely, I thought we could chip away at it one piece at a time (to keep PR size non-overwhelming/reviewable).

If we make some fire under #5574 we can also remove lots of ts-ignore's again (currently it's not possible, because it's considered @interface while typeof requires a "real" class).
