Subject: [PATCH] libobs: Add checks to some graphics API functions

A few recently introduced graphics API functions needed for Enhanced
Broadcasting were marked as `GRAPHICS_IMPORT_OPTIONAL`. Add the
proper checks in the wrapper to ensure they are safe on platforms
that do not implement the underlying function.
