variable.c: reduce heap usage for autoload_data_i
For the loader (first thread which hits autoload, it is wasteful
to have extra elements on the stack. For the lifetime of the
process, it is wasteful to waste 2 words for every autoload
entry. So this makes full use of existing stack overhead
while reducing heap overhead for long-lived autoload_data_i
structs.
* variable.c (struct autoload_state): usable as wait-queue head
(struct autoload_data_i): remove 2 words of overhead
(autoload_i_mark): remove marking for thread
(autoload_reset): adjust for struct changes
(rb_autoload): ditto
(rb_autoloading_value): ditto
(rb_autoload_load): ditto
(const_update): ditto
