c++: Fix decltype of empty pack expansion of parm.

In unevaluated context, we only substitute a single PARM_DECL, not the
entire chain, but the handling of an empty pack expansion was missing that
check.

PR c++/93140
* pt.c (tsubst_decl) [PARM_DECL]: Check cp_unevaluated_operand in
handling of TREE_CHAIN for empty pack.
