Batches don't always provide all required resources for a shader. This can happen when the resource is defined in the shader, but not used in a specific variant. The definition is still there and needs to be filled. This PR adds a dummy buffer to fill the missing attributes. It also fixes an issue when using vertex attributes that uses multiple binding locations (mat4). Pull Request: https://projects.blender.org/blender/blender/pulls/111350
