moved normalizeColor and changed dependencies (#27372)

Summary:
Originally, normalizeColor.js was in Library/Color/ however, I noticed that its tests were in a completely different directly (Library/StyleSheet/__tests__) which was confusing. The other files such as processColor.js, setNormalizedAlphaColor.js had their tests in Library/StyleSheet/__tests__ as well.

## Changelog

[Internal] [Changed] - Moved normalizeColor.js to a more appropriate directory where its tests live.
Pull Request resolved: https://github.com/facebook/react-native/pull/27372

Test Plan: I simply moved a file and changed dependencies. The code should still function as is.
