cairommconfig.h.[in|meson]: Add CAIROMM_API
This macro can be used to decorate public class and API prototypes, so
that we can use it to export symbols with compiler directives, such as
__declspec(dllexport) in the case of Visual Studio-style builds.
We can even decide to not use it by keeping CAIROMM_API empty, such as
in the case of building static libraries or when using GCC's
autoexporting mechanism.
