c++: [[no_unique_address]] fixes. [PR96105]
We were wrongly checking is_empty_class on the result of strip_array_types
rather than the actual field type. We weren't considering the alignment of
the data member. We needed to handle unions the same way as
layout_nonempty_base_or_field.

* class.c (check_field_decls): An array of empty classes is not an
empty data member.
(layout_empty_base_or_field): Handle explicit alignment.
Fix union handling.
