c++: ignore explicit dguides during NTTP CTAD [PR101883]

Since (template) argument passing is a copy-initialization context,
we mustn't consider explicit deduction guides when deducing a CTAD
placeholder type of an NTTP.

PR c++/101883

gcc/cp/ChangeLog:

* pt.c (convert_template_argument): Pass LOOKUP_IMPLICIT to
do_auto_deduction.

gcc/testsuite/ChangeLog:

* g++.dg/cpp2a/nontype-class49.C: New test.
