MSVC: Set proper flags for C++17 support.
MSVC already builds with the /std:c++17 flag but for 'reasons' [1] MSVC still gives the wrong value for the __cplusplus define. This change sets an additional cxx flag on supported compilers to allow the compiler properly identify C++17 support. This resolves 2 warnings coming out of bullet about the register keyword being deprecated. [1] https://devblogs.microsoft.com/cppblog/msvc-now-correctly-reports-__cplusplus/
