…r by default
## Proposed changes
<!--Describe your changes.-->
In the source code of the Doris be module, the default initialization of
pointer member variables in the class is not uniform, and there is no default
initialization, {nullptr},=nullptr. So in this large-scale unification,
use=nullptr to set it.
1. Use = nullptr
- T *
- const T *
- T **
- const T **
- shared_ptr<T>
- unique_ptr<T>
2. Don't set default initialization
- T * const
3. Set {nullptr} to = nullptr
4. Unchanged parts
- extern
- null/NULL
- Customized pointers through using, typedef, and other methods
