[New-bugs-announce] [issue37358] Use vectorcall for functools.partial

[Jeroen Demeyer]

New submission from Jeroen Demeyer <J.Demeyer at UGent.be>:

functools.partial already has some optimizations to use vectorcall (formerly known as fastcall) for its onward calls, so it makes a lot of sense to also use vectorcall when being called.
