Subject: [PATCH] Unify and utilize NPROC variable for Linux setup scripts
 (#11366)

Summary:
This PR unifies the usage of the number of parallel build threads by using the defined NPROC variable. This variable is populated by the same mechanisms on macOS and Linux ensuring consistency and sharable functions for the script refactor.
