V8Update.cmd would fail if vs2019 is installed in drive other than C:

On Windows, the build script (vs_toolchain.py) would fail with message "No supported Visual Studio can be found".
Even I already set the path with $Env:vs2019_install = "d:/my-vs-path", and I can see the value is available with dir env.

Hi @nextfool,

Yes, unfortunately, the Chromium team's build scripts are very finicky, particularly on Windows, as that's not their primary platform. We'll see if we can reproduce this, and if so, we'll post a bug report.

Thank you!
