Enabled android-ndk to work with Python 3.12+

distutils was dropped from Python 3.12. Fortunately, our usage of
android-ndk only relied on distutils.dir_util.copy_tree() in
build/tools/make_standalone_toolchain.py which
is easy to replace with shutil.copytree(). That is done via a small
patch.

Note that there are more references to distutils in the following
files but it looks like our CI/CD flows aren't affected by those:

sources/third_party/shaderc/third_party/spirv-tools/utils/generate_registry_tables.py
