summary:
bpo-45582: Fix test_embed failure during a PGO build on Windows (GH-30014)
This defines VPATH differently in PGO instrumentation builds, to account for a different default output directory. It also adds sys._vpath on Windows to make the value available to sysconfig so that it can be used in tests.
