Original issue's description:
> [tracing] Adding task information to heap profiler
>
> This CL adds more information to the malloc heap profiler added in
> crrev.com/1675183006. The heap profiler only shows trace events and all
> the tasks show up as "MessageLoop::Runtask".
>
> This CL does:
> - Moves TRACE_TASK_EXECUTION macro from task_annotator to
> trace_event.h.
> - Adds extra scoped trace event to track the task context in heap
> profiler.
> - The folder where the task was posted from is used to categorize
> allocations.
> - Uses the type_name for context temporarily till we define a new
> context dimension for allocations.
