Enable refinements on symbol-proc in ruby-level methods

* vm_args.c (refine_sym_proc_call): resolve refinements when the
  proc is invoked, instead of resolving at making the proc, to
  enable refinements on symbol-proc in ruby-level methods

* vm.c (vm_cref_dup): clear cached symbol-procs when duplicating.
