Attachment: Bug 1885910 - [devtools] Avoid duplicated locations being notified by Tracer's onStep option.

isStepStart returned by getOffsetMetadata isn't enough to identify meaningful steps when execution JS instructions.
Fallback on also checking if we moved to another location.
This assumes that we can have the exact same location (line and column) to be executed twice in a row?
There should always be another instruction to run, even in loops.
