[issue46368] faulthandler: add the ability to dump all interpreters, not only the current interpreter

[STINNER Victor]

STINNER Victor  added the comment:

Attached patch is an incomplete quick & dirty implementation to log all 
interpreters in _Py_DumpTracebackThreads().

A better implementation should leave the current behavior unmodified, add a new 
C function, and add all_interpreters=False parameter to the following 
faulthandler functions:

* dump_traceback()
* enable()
* register()

New submission from STINNER Victor :

While debugging the sub-interpreter crash bpo-46070, I noticed that 
faulthandler only logs the Python thread state of a single interpreter. When a 
bug involves multiple interpreters, it is useful to log all interpreters.
