gh-90370: Argument Clinic: avoid temporary tuple creation for varargs (#126064)

Browse source 
Avoid temporary tuple creation when all arguments either positional-only
or vararg.

Objects/setobject.c and Modules/gcmodule.c adapted. This fixes slight
performance regression for set methods, introduced by gh-115112.
