[win-cross] Support using a zip file for the Windows SDK

Browse Source 
Renames DEPOT_TOOLS_WIN_TOOLCHAIN_HTTP_BASE_URL to
DEPOT_TOOLS_WIN_TOOLCHAIN_BASE_LOCATION. This environment variable can
now point to a local directory where the Windows SDK zip file is stored.
This allows non-Googlers to cross-compile Chromium for Windows.
