The stoke shader of grease pencil uses a geometry shader stage. Apple devices don't support shaders with geometry shader stage. In the OpenGL driver there was a pass-through implemented so it didn't fail. When using the metal backend this needs to be solved more explicitly. This change patches the grease pencil shader to support both the backends supporting a geometry stage and those without. Fixes #105059 Pull Request #105116
