c++: Fix ICE with structured binding initialized to incomplete array [PR97878]
We ICE on the following testcase, for incomplete array a on auto [b] { a }; without
giving any kind of diagnostics, with auto [c] = a; during error-recovery.
The problem is that we get too far through check_initializer and e.g.
store_init_value -> constexpr stuff can't deal with incomplete array types.
As the type of the structured binding artificial variable is always deduced,
I think it is easiest to diagnose this early, even if they have array types
we'll need their deduced type to be complete rather than just its element
type.

* decl.c (check_array_initializer): For structured bindings, require
the array type to be complete.
* g++.dg/cpp1z/decomp54.C: New test.
