* vm_core.h (struct rb_iseq_struct), compile.c (iseq_set_arguments), iseq.c (rb_iseq_parameters), vm_insnhelper.c (vm_callee_setup_arg_complex): support Method#parameters for keyword arguments. The provisional spec is what Benoit Daloze proposed. [ruby-core:40518]

* test/ruby/test_keyword.rb: add a test for above.
