[issue40630] tracemalloc: allow resetting peak memory metric without touching other traces

[Huon Wilson]

New submission from Huon Wilson :

Per 
https://mail.python.org/archives/list/python-id...@python.org/thread/QDWI37A4TJXOYUKULGPY2GKD7IG2JNDC/
 , it would be helpful to have a function that resets the peak memory usage of 
the tracemalloc module, without changing all the traces.

This allows for recording the peak memory usage of a specific region of code, 
rather than only the peak since the last tracemalloc.start() or 
tracemalloc.clear_traces() call.
