feat: support json index (#36750)

Browse Source 
https://github.com/milvus-io/milvus/issues/35528

This PR adds json index support for json and dynamic fields. Now you can
only do unary query like 'a["b"] > 1' using this index. We will support
more filter type later.

basic usage:
```
collection.create_index("json_field", {"index_type": "INVERTED",
    "params": {"json_cast_type": DataType.STRING, "json_path":
'json_field["a"]["b"]'}})
```

There are some limits to use this index:
1. If a record does not have the json path you specify, it will be
ignored and there will not be an error.
2. If a value of the json path fails to be cast to the type you specify,
it will be ignored and there will not be an error.
3. A specific json path can have only one json index.
4. If you try to create more than one json indexes for one json field,
sdk(pymilvus<=2.4.7) may return immediately because of internal
implementation. This will be fixed in a later version.
