This reverts commit 9ce8be33.

Reason for revert: To apply fix

Original change's description:
> Revert "Support multiple VS installations"
>
> This reverts commit 36d41cef.
>
> Reason for revert: Script references VS_VERSION variable that was
> renamed in the prior change, so it doesn't work.
>
> Original change's description:
> > Support multiple VS installations
> >
> > Currently, package_from_installed.py assumes only one version of VS is
> > installed. It takes the path of the first installation.
> >
> > This could be incorrect in several ways:
> > - Maybe both 2017 and 2019 (the supported versions) are installed and
> >   although the user specified using 2019, the 2017 path comes first.
> > - Maybe 2019 and 2022 are installed, and the 2022 path is used even
> >   though it isn't supported.
> >
> > This CL fixes that issue by parsing the vswhere.exe output to confirm
> > the VS version matches what the user specified, using its corresponding
> > path.
