vkreplay: too many hash tables in the replayer

[jyangsh]

There are many hash tables(std::unordered_map) for remapping the vulkan handles in the replayer. That is causing cpu-bound in some case. From the profile data below, the most cpu time consumed by vkreplay is for remapping the vulkan handles. Is there any plan for improving the cpu overload in vkreplay?
