fix(compiler)(**BREAKING**): allow using files provided by `tsconfi…

…g` (#1562)

BREAKING CHANGE:

Any custom typing files or files which are needed to be compiled and intended to use with `jest` need to be defined in `files` option of `tsconfig`.

For example
```
// tsconfig.json
{
   // ...other configs
   "files": [
       "my-custom-typings.d.ts".
       "my-global-module.ts"
   ]
}
```
