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:
```ruby
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.
