Adds --auto_platform to download_from_google_storage.

A very common pattern for the users of this script is to have binaries in
three different folders, eg:
some/folder/win/bin.exe
some/folder/mac/bin
some/folder/linux/bin

Instead of using --platform to specify three different paths, we can recognize
this usage and pass in --auto_platform, and then --directory some/folder/ as the
target.

When enumerating files, it will match each individual file to see if they have
(win|mac|linux) as a parent folder name, and filter out non-matching platforms.
