  [Sema][SVE] Reject by-copy capture of sizeless types

Since fields can't have sizeless type, it also doesn't make sense
to capture sizeless types by value in lambda expressions.  This patch
makes sure that we diagnose that and that we use "sizeless type" rather
"incomplete type" in the associated message.  (Both are correct, but
"sizeless type" is more specific and hopefully more user-friendly.)
