simplify some trivial rb_data_type_t callbacks

* process.c (free_exec_arg): remove
  (memsize_exec_arg): ptr is never NULL
  (exec_arg_data_type): use RUBY_TYPED_DEFAULT_FREE

* variable.c (autoload_i_free): remove
  (autoload_data_i_type): use RUBY_TYPED_DEFAULT_FREE
  (autoload_memsize): ptr is never NULL

* vm_backtrace.c (location_free): remove
  (location_mark): ptr is never NULL
  (location_data_type): use RUBY_TYPED_DEFAULT_FREE
  (backtrace_mark): ditto
  (backtrace_free): ditto
