go(BREAKING)!: improve error implmentation

[wenchy]

For gopher, it's recommended to use https://pkg.go.dev/errors. But not home-made error code style.

We should deprecate code and xerrors:

• https://github.com/tableauio/loader/tree/master/test/go-tableau-loader/protoconf/loader/code
• https://github.com/tableauio/loader/tree/master/test/go-tableau-loader/protoconf/loader/xerrors

References:

• https://pkg.go.dev/errors
• https://gorm.io/docs/error_handling.html#Generics-API-1
• https://github.com/redis/go-redis?tab=readme-ov-file#quickstart
