workaround MSVC error
Previous code failed to compile on MSVC. Log:
https://github.com/ruby/ruby/pull/4371/checks?check_run_id=2304484466
This is possibly due to the fact that:
1. `Data_Wrap_Struct(...)` appears in a source code
2. which expands to `rb_data_object_wrap(...)`
3. which expands to `RUBY_MACRO_SELECT(rb_data_object_wrap_, RUBY_UNTYPED_DATA_WARNING)`
4. which expands to `rb_data_object_wrap_0`
5. which expands to `rb_data_object_wrap`, so far so good, but
6. this is a recursive macro expansion (see step 2). Everybody stops expanding...
- in step 4 for MSVC, and
- in step 5 for GCC etc.
I have no idea why but this proposed changeset prevents MSVC from
stopping at step 4.
