VS: Populate Intel -Qstd=c++{14,17} flag table entries

Map them to the `.vcxproj` file `LanguageStandard` setting to quiet our
warning about the setting's default with the Intel toolset in cases that
the project really compiles as C++{14,17}.  This will convert the flags
to `-std:c++{14,17}` but they should be equivalent.
