    gtksourceview/meson.build: Clean up for MSVC
    
    We already require a C99 compiler for gtksourceview-5.x (i.e. Visual Studio
    2015 or later), so there is no need to include a fallback math.h instead of
    the math.h that comes with Visual Studio or the Windows SDK.
    
    We can drop the msvc subdir as a result, and clean up the build files a bit.
