Add wxGetNativeCpuArchitectureName()

This allows to retrieve the native CPU architecture name regardless of
the current process CPU architecture.

Common examples for CPU architecture differences are the following:
    - Win32 process in x64 Windows (WoW)
    - Win32 or x64 process on ARM64 Windows (WoW64)
    - x86_64 process on ARM64 macOS (Rosetta 2)

Closes #22036.
