[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.
