描述

Feature Request

Currently our macros are exported globally. We can make it modular by using the feature "use_extern_macros" so that unnecessary macros are not visible in the scope.

However there some commonly used macros, i.e. info!, warn!. We may create something like "common_macros.rs" and use ::common_macros::* so that it can be easy to use.

研究方向
The issue proposes to utilize the `use extern macros` feature to modularize macro exports. The first step is to research how `use extern macros` works in Rust and identify which macros are commonly used (e.g., info!, warn!). Then, explore the current macro structure in the TiKV codebase, likely located in source files that define macros. Look for existing comments or discussions in the issue #3356 for further guidance. Finally, create a `common macros.rs` file and re export essential macros to clean up the global namespace.
