This commit support a function allows return a field column in named struct column.
Since the function can return any type, this commit also supports ANY_STRUCT_TYPE
and ANY_ELEMENT_TYPE.
In this PR, I have refactored the initialization of the FunctionSet. Previously, all the functions were in one large method which led to the generation of Java code that was too long. This posed a problem for the compiler, as the length of the method exceeded the limit imposed by the Java compiler.
To resolve this issue and improve the readability and manageability of our code, I have categorized these functions by type, and created dedicated initialization methods for each type. As such, our code is now not only more readable and understandable, but also each method is of a length that is acceptable to the compiler and can be compiled successfully.
Moreover, this change makes it easier for us to add new functions as we can directly locate the right category and add new functions there.
This is a significant change aimed at enhancing the maintainability and scalability of our code, while ensuring that our code can be successfully compiled.
To be more compatible with MySQL, rename JSONB type name and function name to JSON.
The old JSONB type name and jsonb_xx function can still be used for backward compatibility.
There is a function jsonb_extract remained since json_extract is used by json string function and more work need to change it. It will be changed further.
Support querying data from the Nebula graph database
This feature comes from the needs of commercial customers who have used Doris and Nebula, hoping to connect these two databases
changes mainly include:
* add New Graph Database JDBC Type
* Adapt the type and map the graph to the Doris type
Add St_Angle/St_azimuth function：
St_Angle：
Enter three point, which represent two intersecting lines. Returns the angle between these lines. Point 2 and point 1 represent the first line and point 2 and point 3 represent the second line. The angle between these lines is in radians, in the range [0, 2pi). The angle is measured clockwise from the first line to the second line.
`
mysql> SELECT ST_Angle(ST_Point(1, 0),ST_Point(0, 0),ST_Point(0, 1));
+----------------------------------------------------------------------+
| st_angle(st_point(1.0, 0.0), st_point(0.0, 0.0), st_point(0.0, 1.0)) |
+----------------------------------------------------------------------+

St_azimuth：
Enter two point, and returns the azimuth of the line segment formed by points 1 and 2. The azimuth is the angle in radians measured between the line from point 1 facing true North to the line segment from point 1 to point 2.
`
mysql> SELECT st_azimuth(ST_Point(0, 0),ST_Point(1, 0));
+----------------------------------------------------+

* Revert "[fix](function) fix AES/SM3/SM4 encrypt/ decrypt algorithm initialization vector bug (#17420)"
This reverts commit 397cc011c4f1ba5a25c770258c13f1cd3f28b47d.
* [fix-resubmit](function) fix AES/SM3/SM4 encrypt/ decrypt algorithm initialization vector bug (#17420)
ECB algorithm, block_encryption_mode does not take effect, it only takes effect when init vector is provided.
Solved: 192/256 supports calculation without init vector
For other algorithms, an error should be reported when there is no init vector
Initialization Vector. The default value for the block_encryption_mode system variable is aes-128-ecb, or ECB mode, which does not require an initialization vector. The alternative permitted block encryption modes CBC, CFB1, CFB8, CFB128, and OFB all require an initialization vector.

Note: This fix does not support smooth upgrades. during upgrade process, query may report error: funciton not found
Inspired by c++ function `std::vector::emplace_back()`, we can use variadic template for this issue.
e.g.
```
[['struct'], 'STRUCT<TYPES>', ['TYPES'], 'ALWAYS_NOT_NULLABLE', ['TYPES...']]
```
`...TYPES` in template_types defines a variadic template `TYPE`. Then the variadic template will be expanded to multiple normal templates based on actual input arguments at runtime in FE.
But make sure `TYPES...` is placed on the last position in all template type arguments.
BTW, the origin template function logic is not affected.
basic functions for map datatype:
- MAP<K, V> map(K k1, V v1, ...)
- BIGINT map_size(MAP<K, V> m)
- BOOL map_contains_key(MAP<K, V> m, K k1)
- BOOL map_contains_value(MAP<K, V> m, V v1)
- ARRAY< K> map_keys(MAP<K, V> m)
- ARRAY< V> map_values(MAP<K, V> m)
* [Feature](vectorized)(quantile_state): support vectorized quantile state functions
1. now quantile column only support not nullable
2. add up some regression test cases
3. set default enable_quantile_state_type = true

Function esquery does not work because there is a problem parsing the first parameter type.
The first parameter, which is SlotRef, will be cast to CastExpr. This will cause error while generating ES DSL.
Add more types to adapt esquery function.
