This PR adds a context function to consider all buffer bindings obsolete. This is in order to track missing binds and invalid lingering states accross `draw::Pass`es. The functions `GPU_storagebuf_debug_unbind_all` and `GPU_uniformbuf_debug_unbind_all` do nothing more than resetting the internal debug slot bits to zero. This is what OpenGL backend does as it doesn't track the bindings themselves. Other backends might have other way to detect missing bindings. If not they should be implemented separately anyway. I renamed the function to `debug_unbind_all` to denote that it actually does something related to debugging. This also add SSBO binding check for OpenGL as it was also missing. #### Future This error checking logic is pretty much backend agnostic. While it would be nice to move it at `gpu::Context` level, we don't have the resources for that now. Pull Request: https://projects.blender.org/blender/blender/pulls/120716
