Move CSSTokenizer to "react/renderer/css" (#42832)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42832

Various analogs to CSS types and utilities currently exist between `core` and `components/view`. These don't really belong well with either, so this adds a top-level "css" library, and moves `CSSTokenizer` there.

This is statically linked into Fabric binary on Android OSS.
