FindPython: ensure user's policies are respected
Do not set the policy version before recording our internal macros such as `__Python_add_library`. Otherwise callers get our policy version instead of theirs. Instead just set the specific policies we need. Also fix one case in our test suite where we were accidentally relying on the policy version to be set by `FindPython`. Fixes: #21042
