ISSUE-21257: set redirectEnd on PerformanceResourceTiming

<!-- Please describe your changes on the following line: -->
Added the appropriate attribute and setters. Included a Timer struct with a `Drop` function to set this value to zero in error cases. Set the value to `responseEnd` on success. Eliminated tests that now pass.
