Following on from the recent upgrade from Jest 26->27, this brings us up to present day Jest 29 for tests of React Native itself, Metro, and Meta-internal code. An update to the template for RN apps will follow.

Summary:
Jest 27 [flips defaults](https://jestjs.io/blog/2021/05/25/jest-27#flipping-defaults), making "modern" fake timers (ie, `sinonjs/fake-timers`) the default, over "legacy", which we currently use.
We're not quite ready for modern timers yet, partly due to Promise polyfills (https://github.com/facebook/react-native/pull/34659), and also some internal issues with specific tests.
This makes our use of legacy timers explicit in preparation for an update to Jest. A switch to modern timers may follow later.

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.

[General][Deprecated] Deprecate the use of `react-native/jest/preprocessor.js` by external projects
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. Some projects are directly using `preprocessor.js` which is part of the testing setup for the React Native repo itself.
In a future release of React Native, we will stop publishing this file to npm and require projects to switch to the supported preset (or a custom Jest config if necessary).

Summary:
**Depends on https://github.com/facebook/react-native/pull/25100**
This commit depends on having migrated all of RN away from Haste. With 100% standard path-based requires, the key foundation is set and we no longer need `hasteImpl` and related settings in the Jest configuration.
This commit deletes the `hasteImpl` file and setting as well as `providesModuleNodeModules` and `modulePathNameMapper`, removing most of the dependency graph overriding performed by Jest.
## Changelog
[General] [Changed] - Delete hasteImpl, providesModuleNodeModules, and modulePathNameMapper from Jest config
