Import Xcode GPU Debugger Plugin for Mac

- This plugin works similarly to the RenderDoc plugin for Windows. Enable the plugin in your project settings, and then press Shift+E to trigger a GPU frame capture of the primary viewport. It will automatically open in Xcode once the capture is complete, at which point you can replay the capture, step through it, etc...
