Add types directory export for each package

[thetarnav]

When selecting a "moduleResolution" option is tsconfig other than "node" you cannot import the other not-exported from main modules types, which is useful for importing a very specific internal type, eg in devtools. 🙃

But when the types directories are explicitly exported one can import a specific .d.ts file.

Another solution would be to export every internal type from main modules, which is fine too.
