Lei, HUANG b19d23d665 fix(mito): revert initial builder capacity for TimeSeriesMemtable (#6231) 
* fix/initial-builder-cap:
 ### Enhance Series Initialization and Capacity Management

 - **`simple_bulk_memtable.rs`**: Updated the `Series` initialization to use `with_capacity` with a specified capacity of 8192, improving memory management.
 - **`time_series.rs`**: Introduced `with_capacity` method in `Series` to allow custom initial capacity for `ValueBuilder`. Adjusted `INITIAL_BUILDER_CAPACITY` to 16 for more efficient memory usage. Added a new `new` method to maintain backward compatibility.

* fix/initial-builder-cap:
 ### Adjust Memory Allocation in Memtable

 - **`simple_bulk_memtable.rs`**: Reduced the initial capacity of `Series` from 8192 to 1024 to optimize memory usage.
 - **`time_series.rs`**: Decreased `INITIAL_BUILDER_CAPACITY` from 16 to 4 to improve efficiency in vector building.
