Move generic HashTreeRoot funcs to //shared (#6167)
* Functions that are to be moved to //shared/htrutils captured in separate file.

* Move files into new //shared/htutils package

hash_function.go renamed to hashers.go

* Refactor to reference moved methods in new package

- Added import for htrutils to state and stateutil packages
- Update references to imported funcs (append "htrutils.")
- Updated funcs in htrutils to be exported where necessary

* Add tests
