Fix compiler warning on Windows (GH-18012)

Fix compiler warning on Windows (GH-18012)

Python-ast.h contains a macro named Yield that conflicts with the Yield macro
in Windows system headers. While Python-ast.h has an "undef Yield" directive
to prevent this, it means that Python-ast.h must be included before Windows
header files or we run into a re-declaration warning. In commit c96be811fa7d
an include for pycore_pystate.h was added which indirectly includes Windows
header files. In this commit we re-order the includes to fix this warning.
(cherry picked from commit e92d39303feb1d3b4194c6a8275b1fc63b2153b2)
