ipa: Dump cgraph_node UID instead of order into ipa-clones dump file

Since starting from GCC 15 the order is not unique for any
symtab_nodes but m_uid is, I believe we ought to dump the latter in
the ipa-clones dump, if only so that people can reliably match entries
about new clones to those about removed nodes (if any).

This patch also contains a fixes to a few other places where we have
so far dumped order to our ordinary dumps and which have been
identified by Michal Jires.

gcc/ChangeLog:
