Deflake invalidation tracking trace event test

The test was flaky because some events that are tested here are not
dispatched for unknown reasons on some instances of the event execution.
This CL aims to reduce flakiness by adding multiple attempts to the
tracing + test scenario flow when the events that are needed aren't
found.

I took the opportunity to incorporate a flaky legacy devtools test into
this test so that we can get rid of it. For this, the stack trace of the
Layout event is checked to ensure it includes the function that caused
the layout
