last piece of solving lifetime constraints for ComputePass

Description
Technically this PR is a bugfix: Previously, when destroying a QuerySet that is used in any way (either write_timestamp, ComputePassTimestampWrites or begin_pipeline_statistics_query) before executing the pass, we would crash.
This solves this as in the PRs before by taking ownership of the query the moment it is provided.

Testing
Adds two new tests that test for gracefully handling destroyed query set before the compute pass is executed.
Both tests failed before the fix.
