method.h: pack rb_method_definition_t struct
We only have 12 method types, so 4 bits is enough for
rb_method_type_t.
Size reductions:
- x86-64 48 => 40 bytes
- x86 28 => 24 bytes
* method.h (enum method_optimized_type): split out for CPP
(struct rb_method_definition struct): pack on unaligned systems
(rb_method_definition_t): split typedef to help ctags
[ruby-core:81236] [Feature #13494]
