fix(test runner): more friendly test duration (#15476)

fix(test runner): more firendly test duration

Reported test duration now does not include time spent in
`beforeAll`, `afterAll` and fixtures that have a separate timeout.

This is to avoid different reported test execution time,
depending on the test execution order.
