feat: export ts-jest public apis from index.js (#3080)

Closes #3045 

DEPRECATION
* Import internal `ts-jest` stuffs from `ts-jest/<sub_path>` is discouraged. Users should switch to `import <name> from 'ts-jest'` instead.

* Deprecation import path `import <name> from 'ts-jest/utils'`. Users should switch to `import <name> from 'ts-jest'` instead.
