[issue32532] improve sys.settrace and sys.setprofile documentation

[Xiang Zhang]

New submission from Xiang Zhang <angwerzx at 126.com>:

I propose to mention the behaviour that "if exception raised in tracefunc or profilefunc, the handler will be unset" in the documentation of sys.settrace and sys.setprofile. I encounter this behaviour and surprised by it since I can't get the info from the doc. Only by digging into the source code, I can find out why the profile messages suddenly disappear.
