Use modern C++ casts instead of current C-style casting approaches

### Description

Update various API implementations that use c-style pointer casting and other c-style approaches to use modern C++ casts.

### Is this a breaking change?

The function signatures would remain unchanged
The behavior of the functions would be identical
User code that calls these functions wouldn't need any modifications

### Additional information

Modernizes the code base. Compilers will optimize these the same, but coding standards favor using C++ cast in C++ code.

首先定位使用 C-style pointer casts 或其他 C-style casting approaches 的 API 实现。将相关的 casts 替换为 modern C++ casts，同时保持 function signatures 和行为不变，然后验证这些实现仍能成功构建且行为完全一致。
