feat: Add json flat index (#39917)
issue: https://github.com/milvus-io/milvus/issues/35528

This PR introduces a JSON flat index that allows indexing JSON fields
and dynamic fields in the same way as other field types.

In a previous PR (#36750), we implemented a JSON index that requires
specifying a JSON path and casting a type. The only distinction lies in
the json_cast_type parameter. When json_cast_type is set to JSON type,
Milvus automatically creates a JSON flat index.

For details on how Tantivy interprets JSON data, refer to the [tantivy
documentation](https://github.com/quickwit-oss/tantivy/blob/main/doc/src/json.md#pitfalls-limitation-and-corner-cases).

Limitations
Array handling: Arrays do not function as nested objects. See the
[limitations
section](https://github.com/quickwit-oss/tantivy/blob/main/doc/src/json.md#arrays-do-not-work-like-nested-object)
for more details.

fix: fix concurrent issues in null offset (#40363)
issue: #40308
This issue fixes these two concurrent issues:
1. element in null_offset is used to set bitset where the size of bitset
is initialized by tantivy document count. However, there may still be
some documents that are not committed in tantivy but are null in
null_offset. So array out of range occurs.
2. null_offset can be read and write concurrently but there's no
synchronization protection.

feat: support json index (#36750)
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.
