Problem: win32: python3 dll loading can be improved
Solution: Load DLL from registry path
Support loading python3.dll and/or python3xx.dll from the path written
in the registry. To support Stable ABI's forwarder DLL (python3.dll),
use the `LOAD_LIBRARY_SEARCH_DLL_LOAD_DIR` flag for `LoadLibraryExW()`
because python3xx.dll is placed in the same directory of python3.dll.
If Stable ABI is used, search the latest version from the registry (both
from HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE). If Stable ABI is not
used, search only the matching version.
