CMakeLists: Make use of /std:c++latest on MSVC

Provides the buildbot with one builder that is always tracking the
latest version of the C++ standard, allowing us to progressively rectify
our code and amend any differences between standards over time instead
of waiting for a complete standard change, potentially breaking a lot of
code all at once.
