[Scons-dev] MSVC 2017+ Toolset Support

[Joseph Brill]

The was a previous iteration that allowed MSVC_VERSION to contain a toolset
and added a MSVC_PRODUCT variable that could contain a product
specification and optional component type.

This was described in:
https://github.com/SCons/scons/issues/3664#issuecomment-643782430

Unfortunately, this predates the code being added to version control as it
was a proof-of-concept that evolved fairly rapidly.
