c++: Add CTAD + pack expansion testcase

After r11-6614 made cp_walk_subtrees walk into the template of a CTAD
placeholder, we now correctly accept the below testcase.  We used to
reject it because find_parameter_packs_r would fail to find the
parameter pack Ts inside the CTAD placeholder within the pack expansion.

gcc/testsuite/ChangeLog:

* g++.dg/cpp1z/class-deduction77.C: New test.
