c++: Fix unhiding friend with imports [PR 99248]

This was a simple thinko about which object held the reference to the
binding vector.  I also noticed stale code in the tree dumper, as I
recently removed the flags from a lazy number.

	PR c++/99248
	gcc/cp/
	* name-lookup.c (lookup_elaborated_type_1): Access slot not bind
	when there's a binding vector.
	* ptree.c (cxx_print_xnode): Lazy flags are no longer a thing.
	gcc/testsuite/
	* g++.dg/modules/pr99248.h: New.
	* g++.dg/modules/pr99248_a.H: New.
	* g++.dg/modules/pr99248_b.H: New.
