Implement P0780R2, pack expansion in lambda init-capture.
Mostly this was straightforward; the tricky bit was finding, in the
instantiation, the set of capture proxies built when instantiating the
init-capture. The comment in lookup_init_capture_pack goes into detail.
* parser.c (cp_parser_lambda_introducer): Parse pack init-capture.
* pt.c (tsubst_pack_expansion): Handle init-capture packs.
(lookup_init_capture_pack): New.
(tsubst_expr) [DECL_EXPR]: Use it.
(tsubst_lambda_expr): Remember field pack expansions for
init-captures.
