Description
Enhancement
In TiFlash we use fmt library to serialize a bunch of objects, but we don't support formatting User-defined types.
We can implement format method for our user-defined types by specializing the formatter struct template.
Can ref to https://fmt.dev/latest/api.html?highlight=fmt%20formatter#formatting-user-defined-types.

Research direction
Start with the fmt.dev documentation on formatting user-defined types, then inspect TiFlash's existing fmt-based serialization sites. Identify which user-defined types are in scope and how their current formatting is covered; done means the agreed types support fmt formatter customization with corresponding coverage.
