Aliaksandr Kalenik 0ff29349e6 LibJS: Add GC graph dumper 
This change introduces a very basic GC graph dumper. The `dump_graph()`
function outputs JSON data that contains information about all nodes in
the graph, including their class types and edges.

Root nodes will have a property indicating their root type or source
location if the root is captured by a SafeFunction. It would be useful
to add source location for other types of roots in the future.

Output JSON dump have following format:
```json
    "4908721208": {
        "class_name": "Accessor",
        "edges": [
            "4909298232",
            "4909297976"
        ]
    },
    "4907520440": {
        "root": "SafeFunction Optional Optional.h:137",
        "class_name": "Realm",
        "edges": [
            "4908269624",
            "4924821560",
            "4908409240",
            "4908483960",
            "4924527672"
        ]
    },
    "4908251320": {
        "class_name": "CSSStyleRule",
        "edges": [
            "4908302648",
            "4925101656",
            "4908251192"
        ]
    },
