Go-to-definition doesn't work on non-module packages

[DanielRosenwasser]

If you have @types/node installed, you might naively try to go-to-definition on node in the following code if you're trying to understand things better.

import "node";

Similarly to what used to happen with go-to-definition on a non-module file (#41861), we don't find a corresponding symbol for the module and just give up.

However, we were able to get this partially working for relative source files in #42539. We should be able to still make this work for package files as well.

Hello @DanielRosenwasser , if no one is working on this bug. can I give it a stab ?

[DanielRosenwasser]

Sure, though as a warning I think it's not likely to be an easy bug to get right in a clean way.
