Bug #17554: [PATCH] Fix ObjectSpace.dump to include singleton class name

Patch: https://github.com/ruby/ruby/pull/4087
This fixes a regression introduced in https://bugs.ruby-lang.org/issues/17044
In 2.7.2 `rb_class2name` would go up the inheritance chain to get a name for singleton classes. In 3.0 it no longer works:
2.7.2:
```
$ ruby -robjspace -e 'puts ObjectSpace.dump(Object.new.singleton_class)'
{"address":"0x7fca778cdab8", "type":"CLASS", "class":"0x7fca738bfbb0", "name":"Object", "references":["0x7fca778cdb30", "0x7fca738c57b8"], "memsize":456, "flags":{"wb_protected":true}}
```
3.0.0:
```
$ ruby -robjspace -e 'puts ObjectSpace.dump(Object.new.singleton_class)'
{"address":"0x7fdf440a7cd0", "type":"CLASS", "class":"0x7fdf408c9728", "references":["0x7fdf408ca8a8", "0x7fdf440a7d70"], "memsize":472, "flags":{"wb_protected":true}}
```
This name is very useful for https://github.com/Shopify/heap-profiler.
