enhance: reorder sub expr for conjunct expr (#39872)
two point:
 (1) reoder conjucts expr's subexpr, postpone heavy operations
sequence: int(column) -> index(column) -> string(column) -> light
conjuct
...... -> json(column) -> heavy conjuct -> two_column_compare
(2) support pre filter for expr execute, skip scan raw data that had
been skipped
     because of preceding expr result.

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.

feat: Implement custom function module in milvus expr (#36560)
OSPP 2024 project:
https://summer-ospp.ac.cn/org/prodetail/247410235?list=org&navpage=org

Solutions:

- parser (planparserv2)
    - add CallExpr in planparserv2/Plan.g4
    - update parser_visitor and show_visitor
- grpc protobuf
    - add CallExpr in plan.proto
- execution (`core/src/exec`)
- add `CallExpr` `ValueExpr` and `ColumnExpr` (both logical and
physical) for function call and function parameters
- function factory (`core/src/exec/expression/function`)
    - create a global hashmap when starting milvus (see server.go)
- the global hashmap stores function signatures and their function
pointers, the CallExpr in execution engine can get the function pointer
by function signature.
- custom functions
    - empty(string)
    - starts_with(string, string)
- add cpp/go unittests and E2E tests

feat: support chunked column for sealed segment (#35764)
This PR splits sealed segment to chunked data to avoid unnecessary
memory copy and save memory usage when loading segments so that loading
can be accelerated.

To support rollback to previous version, we add an option
`multipleChunkedEnable` which is false by default.

enhance: Custom bitset and bitsetview prototypes (#30454)
Issue: #31285 

Basically, I've replaced `FixedVector<bool>` and `boost::dynamic_bitset`
with custom bitset and bitsetview in order to reduce the memory
bandwidth & increase performance for the filtering.

This PR is for internal use only. 

Current progress (numbers are for GCC 9.5.0 on Ubuntu 22.04 LTS;
clang-17 produces better performance numbers):

enhance: full-support for wildcard pattern matching (#30288)
issue: #29988 
This pr adds full-support for wildcard pattern matching from end to end.
Before this pr, the users can only use prefix match in their expression,
for example, "like 'prefix%'". With this pr, more flexible syntax can be
combined.

To do so, this pr makes these changes:
- 1. support regex query both on index and raw data;
- 2. translate the pattern matching to regex query, so that it can be
handled by the regex query logic;
- 3. loose the limit of the expression parsing, which allows general
pattern matching syntax;

With the support of regex query in segcore backend, we can also add
mysql-like `REGEXP` syntax later easily.
