Introduce GPU checkpoints for crash debugging

Browse Source 
When GPU crashes aren't reproducable in renderdoc, it helps to have someway to figure out what exactly is going on when a crash happens or what operation caused it. Add a checkpoint system that reports the GPU execution state in perfetto in time with actual GPU execution, and use flow events to show the event's path through execution, vulkan record and executor record stages.
