Add a platform filtering and executable setting abilities to download_from_google_storage.
Adds a command line flag --platform to control which platforms the given download occurs on.
Automatically marks downloads executable on non-Windows if the header x-goog-meta-executable is set. Automatically set this flag on upload when the executable bit is set.
