fix(jest): restore RefreshControl mock to fix tests in RN 0.80 (Fixes: #52152)

[Aarshpatel12]

This PR fixes a regression introduced in React Native 0.80.0 where Jest tests fail due to a missing RefreshControlMock file.

The mock was removed in #50784 when .npmignore files were replaced, causing a missing reference during Jest setup. This impacts not just core tests, but also third-party libraries such as react-native-gesture-handler and react-native-drawer-layout that depend on this mock during testing.

Changelog

[Internal] Fixed missing Jest mock for RefreshControl causing test failures in React Native 0.80.0.

Test Plan

• Restored RefreshControlMock.js in Libraries/Components/RefreshControl/__mocks__
• Ran yarn test locally on both macOS and Windows — all test suites and snapshots passed
• Confirmed the file is included in npm pack and not ignored

Fixes: #52152

There seem to be more changes here than just the RefreshControlMock. Please revert those.

#51669 moved the refresh control mock to https://github.com/facebook/react-native/blob/main/packages/react-native/jest/mocks/RefreshControl.js

we can't accept this fix. The snapshots have been updated in a windows machine and all of them now use \ as path separators insteado of /. This will break tests internally as in CI we run them using linux based machines.
