-Subject: [PATCH] Use the identified python when building
- System.Private.CoreLib (#19043)
-
-build.sh and build.cmd contain logic to identify a working version of
-python to use. System.Private.CoreLib ignores that and directly invokes
-'python', which may not work, or even execute a different program.

-Subject: [PATCH] Support building with python3 on unix (#19356)
-
-The windows build scripts try finding python in order of python3,
-python2 and then python. The unix build scripts dont. They just try
-python2 variants and then fail. This change makes brings them closer
-together by letting users build using only python3.
