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.
