A missed piece of the patch for static operator(): in tsubst_function_decl,
we don't want to replace the first parameter with a new closure pointer if
operator() is static.

	PR c++/108526
	PR c++/106651

gcc/cp/ChangeLog:

	* pt.cc (tsubst_function_decl): Don't replace the closure
	parameter if DECL_STATIC_FUNCTION_P.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp23/static-operator-call5.C: Pass -g.
