c++: pack in enumerator in lambda [PR100198]

The GCC 8 lambda overhaul fixed most uses of lambdas in pack expansions,
but
local enums and classes within such lambdas that depend on parameter packs
are still broken.  For now, give a sorry instead of an ICE or incorrect
error.

gcc/cp/ChangeLog:

* parser.cc (cp_parser_enumerator_definition): Sorry on parameter
pack in lambda.
(cp_parser_class_head): And in class attributes.
* pt.cc (check_for_bare_parameter_packs): Sorry instead of error
in lambda.

gcc/testsuite/ChangeLog:

* g++.dg/cpp0x/lambda/lambda-variadic13.C: Accept the sorry
as well as the correct error.
* g++.dg/cpp0x/lambda/lambda-variadic14.C: Likewise.
* g++.dg/cpp0x/lambda/lambda-variadic14a.C: New test.
* g++.dg/cpp0x/lambda/lambda-variadic15.C: New test.
* g++.dg/cpp0x/lambda/lambda-variadic16.C: New test.

g++-12.0.0-alpha20210530 snapshot (g:a0a7adeea31918deefb053a9a15257af94aecfaf)
rejects the testcase w/o ICE.
