RFR: 8055: Improvement in stacktrace view for Duration

Thu Mar 9 21:42:10 UTC 2023

1. Added a new column for Duration. It will be populated only when the "Show Duration" toggle icon is clicked. Not by default.
2. Fixed NaN issue for screens where duration is not present.
3. Added timeunit to make tooltip more meaningful.

Please refer JIRA description for more details.
