Auto merge of #135281 - onur-ozkan:build-stamps, r=jieyouxu 

centralize build stamp logic

This PR brings all the stamp file handling into one place inside `build_stamp` module, which takes care of everything related to build stamps. By doing this, we cut down on duplicated code and types and keep the codebase easier to maintain and more consistent.

Main goals are:

- Make stamp handling stricter so we don't have to pass `Path`s around and manually `join` on arbitrary directories
- Keep all stamp-related logic in one place
- Make it easier to test and debug
- Avoid duplication
- Keep things simple and well-documented
