internal/imports: cache GOPATH, exports

We intend to use the GOPATH resolver's results during LSP
autocompletion. That means we have to be able to cache its data, same as
we do for modules. Convert it to use a dirInfoCache.

Cache exports in the dirInfoCache. Along the way, store exports as slices
rather than maps. We don't need the extra structure the vast majority of
the time, and the memory overhead is nontrivial.
