[refactor][vectorized] refactor first/last value agg functions At the beginning, the implementation of **first/last value** is used for window functions, and **lead/lag** is also mixed in the implementation; Later, when aiming at the **replace** model, also borrowed the basic implementation of first/last and made some changes.
