meson: Don't use gendef on Visual Studio

Instead, we use the newly-added CAIROMM_API which is defined to be
__declspec(dllexport) to export the symbols directly.

This will also allow some cleanup in the Meson build files, as we do not
need to differentiate how the cairomm library is built on different
compilers.
