feat(tsconfig) added isolated modules flag and fixed types exports

[kociolekscramjet]

Two main issues at babel-loader and ts-loader regarding this task babel/babel-loader#603 TypeStrong/ts-loader#751

To summarize ts-loader works with transpileOnly option which essentially is --isolatedModules. That means ts-loader do not know which re-exported element is type and which is not.

There are workarouns for this.

1. Turn off config.module.strictExportPresence and supress warnings with

     messages = formatWebpackMessages(
          stats.toJson({
            (...)
            warningsFilter: [
              /export .* was not found in/
            ]
          })
        );

2. Or use more precise re-exports (without the *) for example

BAD:

export * from "./a";

GOOD:

import { T } from "./a";
export type T = T;

For now trying second approach with
export type instead of export
