method.h: pack rb_method_definition_t struct

Browse source 
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]
