Fix timestamp writing and resolving from different encoders

Browse Source 
Currently the queries availability info is only stored on the encoders
where they are written, and we need the info in the compute shader. If
resolving them from a different encoder, 0s are returned because the
queries are not written on resolving encoder.

Besides the encoders, we also need to add availability info to query
set, and use it in compute shader instead.

When resolving query set without any written, we need to reset queries
before resolveQuerySet based on the query set availability on Vulkan.

Added more end2end tests for these cases.
