Feature #15031: T_RANGE for testing whether object is a Range

Range is an in-built type of Ruby and it would be better for C extension
writers if there existed a constant T_RANGE that could be directly used
for checking whether a VALUE is a Range.

Currently we need to write CLASS_OF(obj) == rb_cRange in order to make this
happen. Having a T_RANGE would help in making C code more idiomatic and fast
in some cases.

That way, one can write RB_TYPE_P(obj, T_RANGE).

rb_obj_is_range() can be accepted like rb_obj_is_proc and so on.
T_xxx shows data layout of RVALUE.
