abc_new: Support abc9_box mode on ordinary design hierarchy
...
Previously the `abc9_box` mode was reserved to modules with the
`blackbox` or `whitebox` attribute. Allow `abc9_box` on ordinary modules
when doing hierarchical synthesis.

abc9_ops -prep_box: Adjust for repeated invocation
...
`abc9_ops -prep_box` command interprets the `abc9_box` attribute and
prepares a .box file for ABC consumption. Previously this command was
removing the attribute as it was processing each module which prevented
repeated invocation of this command unless the box definitions were
refreshed from a source file.
Also the command was keeping existing `abc9_box_id` attributes instead
of overwriting them with values from a new number sequence.
Change both behaviors to allow repeated invocations of the command on
the same design.

Reduce comparisons of size_t and int
...
`Const::size()` returns int, so change iterators that use it to `auto` instead of `size_t`.
For cases where size is being explicitly cast to `int`, use the wrapper that we already have instead: `Yosys::GetSize()`.
