c1fc4450 - gh-155373: Inline the parsing code of optional groups in Argument Clinic (GH-155374)

gh-155373: Inline the parsing code of optional groups in Argument Clinic (GH-155374) Instead of one PyArg_ParseTuple() call per number of arguments, generate the inlined code of the converters, as for all other parsing methods. Every argument is parsed once. Such functions now use the fastcall convention, except for constructors and other functions which need a tuple.
