Added posix and windows runner scripts for download_from_google_storage.py

Added posix and windows runner scripts for download_from_google_storage.py

Windows bots are having trouble calling download_from_google_storage.py from the
DEPS hooks.  This should allow it to be called as just "download_from_google_storage".

From what I can tell, Goma canary windows bots are rather stubborn about calling
"download_from_google_storage.py" or "python download_from_google_storage.py"
from the C:\b\ directory.

Hopefully adding in this will help fix that.

While I don't mind having these scripts, so lgtm, I'd prefer the actual problem
to be fixed. I think gclient runhooks replaced 'python' with sys.executable.

The main issue afaik is that when you call "python some_script.py", windows
doesn't look in PATH or PYTHON_PATH for some_script.py.

Yeah, that's why I thought I (?) had coded so that CMDrunhooks replace 'python'
for sys.executable before running the hooks.
