6473fbf2 - [CMake][Release] Refactor cache file and use two stages for non-PGO builds (#89812)

[CMake][Release] Refactor cache file and use two stages for non-PGO builds (#89812) Completely refactor the cache file to simplify it and remove unnecessary variables. The main functional change here is that the non-PGO builds now use two stages, so `ninja -C build stage2-package` can be used with both PGO and non-PGO builds.
