Unify SystraceSection.h implementation (#35353)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/35353

Unfortunately we have 2 different definitions of SystraceSection.h
- xplat/js/react-native-github/ReactCommon/cxxreact/SystraceSection.h
- xplat/js/react-native-github/ReactCommon/react/renderer/debug/SystraceSection.h

The first one is the Old Arch one and the second one is the New Arch one.
