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:

2025-05-16  Martin Jambor  <mjambor@suse.cz>

	* cgraph.h (symtab_node): Make member function get_uid const.
	* cgraphclones.cc (dump_callgraph_transformation): Dump m_uid of the
	call graph nodes instead of order.
	* cgraph.cc (cgraph_node::remove): Likewise.
	* ipa-cp.cc (ipcp_lattice<valtype>::print): Likewise.
	* ipa-sra.cc (ipa_sra_summarize_function): Likewise.
	* symtab.cc (symtab_node::dump_base): Likewise.
