Revert "Switch to VS 2017 15.7.1 with 10.0.17134.0 SDK"

This reverts commit 5a7f3c442684be5eeb244b904bbfc8e6edaf6fda.

Reason for revert: this breaks v8's VC++ goma builds, reverting until
goma is updated to support this compiler

Original change's description:
> Switch to VS 2017 15.7.1 with 10.0.17134.0 SDK
> 
> This change switches the VS 2017 package to use VS 2017 Update 7.1 while
> using the 10.0.17134.12 SDK. The new SDK is needed to support new HDR
> features, and to stop forcing external developers to install an old
> ([Spring] Creators Update) SDK. This change will also bring in a new
> linker and other build tools, but the version of clang-cl will be
> unchanged.
> 
> Packaging was done on a Windows Server 2016 VM, cleanly created for this
> purpose.
> 
> Compiler was packaged up by downloading VS 2017 Update 7.1, from
> https://www.visualstudio.com/vs/, and then passing these parameters to
> the installer:
> 
>     --add Microsoft.VisualStudio.Workload.NativeDesktop
>     --add Microsoft.VisualStudio.Component.VC.ATLMFC --includeRecommended
>     --passive
> 
> Then Add or Remove Programs was used to modify the 10.0.17134.0 SDK to add
> the Debuggers package.
> 
> Then the packaging script was run like this:
> 
>   python depot_tools\win_toolchain\package_from_installed.py 2017 -w 10.0.17134.0
