    Inherit `MRB_FL_UNDEF_ALLOCATE` in subclasses · 2a1ea7d6

    If `Class#allocate` is prohibited, subclasses should also be implicitly prohibited.

```ruby
p Class.new(Struct).allocate.class
# => #<Class:0x82362ac00>                                             by #6122
# => allocator undefined for #<Class:0x000000083a983220> (TypeError)  by Ruby 3.2
```

Added `MRB_DEFINE_ALLOCATOR()` to allow subclasses to use `Class#allocate`.

Supplement to #6122.
