[MOB-10126] Improve Test Files Structure (#784)

* Change test directory name to `tests`

* Change `tests` directory structure so it mirrors `src` structure

* Move mocks to `tests/mocks` instead of `tests/jest`

* Move setup code into `setup-tests.js`

* Use recommended native modules mocking technique

* Move `InstabugUtils` tests to root tests directory

* Remove example app unit tests

* Change `Platform.constants ??=` to an if check

* Rename all `NativeIBG*` to `Native*` in tests

* Rename `__e2e__` to `e2e` and follow file naming convention

* Rename `setup-tests.js` to `setup.js`
