OpenGL: Mask out all color outputs with no fragment shader (#6341)

Browse source 
* OpenGL: Mask out all color outputs with no fragment shader

This appears to match Vulkan's behaviour, which is needed for stencil shadows in Penny's Big Breakaway. It's far from the only issue, you can try the Full Bindless PR if you want to see it in a more intact state.
