c++: Aggregate CTAD and string constants.

In CWG discussion, it was suggested that deduction from a string literal
should be to reference-to-const, so that we deduce 'char' rather than 'const
char' for T.

gcc/cp/ChangeLog:

* pt.c (collect_ctor_idx_types): Add 'const' when deducing from
a string constant.

gcc/testsuite/ChangeLog:

* g++.dg/cpp2a/class-deduction-aggr7.C: New test.
