Query API: Record used query index in command encoder

- There are some methods need to know which query indexes are used in
encoders: endOcclusionQuery, endPipelineStatisticsQuery, resolveQuerySet.
- On Vulkan, we also need to use the used query indexes to reset each
queries between uses. And because the reset command must be called
outside render pass, we need to check whether a query index is writen
twice on command encoder and render/compute encoders.
- Add validation on writeTimestamp for duplicate writes at same index.
