Migrate Jest setup scripts from Haste to path-based requires (#24753)

Summary:
This is another step in moving RN towards standard path-based requires. All the requires in Jest's setup script have been rewritten to use relative requires. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.

[General] [Changed] - Migrate Jest setup scripts from Haste to path-based requires
