thread.c: micro-optimize thread create/join
* thread.c (struct join_arg): restructure and make smaller
(thread_join_sleep): avoid timeofday() call if forever
(thread_join): pass join_arg.delay directly
(rb_thread_inspect_msg): remove, inline into rb_thread_inspect
(rb_thread_inspect): reduce branching and string creation
* thread_pthread.c (native_set_thread_name): create string directly
to avoid reparsing. [Misc #10723]
This reduces time in benchmark/bm_vm_thread_create_join.rb by
a few percent.
Minor improvements only:
