David Majnemer afefe97e1c CodeGen: ConstStructBuilder must verify packed constraints after padding ...

Before, ConstStructBuilder::AppendBytes would check packed constraints
prior to padding being added before the field's offset.  However, adding
this padding might force our struct to be packed.  Because we wouldn't
check *after* adding padding, ConstStructBuilder would be in an
inconsistent state leading to a crash.

This fixes PR21300.
