Request: support frame capture API

[Michael-Lfx]

Maybe we can expose start_frame_capture() and end_frame_capture() as public API. For Metal MTLCaptureManager. RenderDoc for Vulkan.

Good point. We will look into it

Thank you. I have managed to implement the functionality on my local dev env.

If you have a PR for it, we could integrate that in our Gitlab repo and have it available in the next public release
