The Vulkan spec states:
* "If the query does not become available in a finite amount of time
(e.g. due to not issuing a query since the last reset), a
VK_ERROR_DEVICE_LOST error may occur."
* "If queries will never finish (e.g. due to being reset but not
issued), then vkGetQueryPoolResults may not return in finite time."
UAV counter descriptors are stored in a separate VkDescriptorSet.
A VkPipelineLayout created for compute pipeline is compatible for all
other descriptor sets with the VkPipelineLayout created for the root
signature. This ensures that only UAV counter bindings in the last
descriptor set may be disturbed when switching between pipelines with
compatible root signatures.
The implementation of vkd3d_popcount() is based on
