Feature #13001: Add `full` option to `ObjectSpace.dump_all`

I would like to include T_NONE slots in the ObjectSpace.dump_all outpout so that I can visualize heap fragmentation. I've attached a patch that adds a "full" option to dump_all so that all slots are dumped to the JSON output, including T_NONE.

Thanks.

Add full option to ObjectSpace.dump_all

The full option includes all slots (even T_NONE) in the JSON output.
This is to help with debugging heap fragmentation.

Here is an example usage:

File.open('heap.json', 'w') do |f|
  ObjectSpace.dump_all(output: f, full: true)
end

The heap.json file contains all slots, including empty slots.
