Bill Currie ea2fd32228 [renderer] Merge screenshot code as much as possible
Only CaptureBGR is per-renderer as the rest of the screenshot code uses
it to do the actual capture (which is target dependent). Vulkan is
currently broken due to capture being an asynchronous process and the
rest of the code expecting capture to be synchronous (also, bgr vs rgb).

The best thing is all renderers now write the same format (currently
png).
