meson/MSVC builds: Use -utf-8 where available

Browse Source 
This avoids the build from erroring out on C4819 (Unicode handling issue in
Visual Studio compiler), notably when running on Chinese, Japanese and
Korean locales.

Also apply -D_USE_MATH_DEFINES, -FImsvc_recommended_pragmas.h and -utf-8 to
the C++ compiler options as well.
