[SPARK-26226][SQL] Update query tracker to report timeline for phases
## What changes were proposed in this pull request?
This patch changes the query plan tracker added earlier to report phase
timeline, rather than just a duration for each phase. This way, we can easily
find time that's unaccounted for.
## How was this patch tested?
Updated test cases to reflect that.
