This is to improve debugging on older hardware that may not support 4.3 debug capabilities (like Macs). This avoids sprinkling glGetErrors manually. This might still be needed to find the root cause since not all functions are covered. This overrides the functions pointers that GLEW have already init. This is only enabled if using --debug-gpu option and the debug extension are not available. This also cleanup the usage of GLContext::debug_layer_support and use wrapper to set object labels.
