Detailed Description

Create an updated VS toolchain

Before you can run this script, you need a collated VC toolchain + Windows SDK.
To generate that, run depot_tools/win_toolchain/package_from_installed.py
That script pulls all of the compiler and SDK bits from your locally installed
version of Visual Studio. The comments in that script include instructions on
which components need to be installed (C++, ARM64, etc...)

That script produces a .zip file with a SHA filename. Unzip that file, then
pass the unzipped directory as the src_dir to this script.
