3e10e5af39 [Fix](Serde) Fix content displayed by complex types in MySQL Client (#25946)
This pr makes three changes to the display of complex types:
1. NULL value in complex types refers to being displayed as `null`, not `NULL`
2. struct type is displayed as "column_name": column_value
3. Time types such as `datetime` and `date`, are displayed with double quotes in complex types. like
    `{1, "2023-10-26 12:12:12"}`

This pr also do a code refactor:
1. nesting_level is set to a member variable of the `DataTypeSerDe`, rather than a parameter in methods.

What's more, this pr fix a bug that fileSize is not correct, introduced by this pr: #25854

a79b8ede88 [Bug](ColumnArray) Fix array column replicate replicate_offsets not matched (#17616)
the input replicate_offsets should be the same size as ColumnArray's offset.
```
IColumn::Offsets replicate_offsets(get_offsets().size(), 0);
// |---------------------|-------------------------|-------------------------|
// [0, begin)             [begin, begin + count_sz)  [begin + count_sz, size())
//  do not need to copy    copy counts[n] times       do not need to copy
```

8bfb89c100 [feature-wip](array-type) Add some regression tests for nested array (#12322)
#11392 made _input_block in each BetaRowsetReaders sharable. However, for some types (e.g. nested array with more than 1 depth), the _column_vector_batches in RowBlockV2 can be nested which means that there is a ColumnVectorBatch inside another ColumnVectorBatch. In this case, the data of inner ColumnVectorBatch
may be corrupted because the data of _input_block is copied shallowly to the _output_block.
