Windows, windows_cc_configure.bzl: Pass -vcvars_ver flag only when it is supported.

Previously, we assume -vcvars_ver is always supported from VS 2017, but it is only introduced from Visual Studio 2017 15.3
https://docs.microsoft.com/en-us/visualstudio/releasenotes/vs2017-relnotes-v15.3?#-visual-c-toolset-and-libraries

As documented, the full VC build tools is 14.11.25503. If the VCVARSALL.bat is from a previous version, we should not pass the -vcvars_ver flag.
