4cec3a0467 Backends: support for multiple imgui context with little testing (#586, #1851, #2004, #3012, #3934, #4141)

This is NOT enable multi-contexts for any backends

Some of the viewport ideas from #2766 are not in there yet (e.g. Vulkan: setting compositeAlpha based on cap.supportedCompositeAlpha)
