cpp: Fix cpp_std=vc++14

Fixes a regression introduced in commit d37d649b08b8 "Make all Meson level
options overridable per subproject." This change results in every file
printing the warning "cl : Command line warning D9002 : ignoring unknown
option '/std:vc++14'"

Now that "get_option_..." is called before overwriting the option (instead
of after), we have to operate on compiler options, not meson options.

There is no such compiler option as /std:vc++14 (the meson option vc++xx is
split into /std:c++xx for the C++ standard version, and a separate flag
that enables Microsoft extensions). Remove the mapping from c++14 to
vc++14.
