[Internal][Changed] - Remove babel plugins from jest preprocessor which are part of preset metro-react-native-babel-preset
Transformer metro-react-native-babel-transformer has preset metro-react-native-babel-preset which has necessary plugins to transpile the source. So we don’t need to pass it again in the preprocessor.
As part of the change, updated one test to use strict mode since metro-react-native-babel-preset has strictMode is set to false.

Changelog:
[Breaking][General] Remove jest/preprocessor from the react-native package
Using `react-native/jest/preprocessor` outside of the React Native repo has been deprecated since D34820086 (https://github.com/facebook/react-native/commit/c1e9aa9a272aed3cba60c4aeff783eeb8bffce68). Here, we make this file private and stop publishing it to npm.
The supported method of using Jest in React Native projects is using the [Jest preset](https://jestjs.io/docs/tutorial-react-native) shipped as part of the `react-native` package.
NOTE: We could probably make some of the other files under `jest/` private as well, but we should go through a separate deprecation cycle with those, in case they are also being used externally by some projects. I'm leaving that for future followup at the moment.
