[wddevries]

What problem does this PR solve?

Issue Number: close #29026

Problem Summary:

There are two copies of most error codes and error messages. This pull request:

• moves the struct mysql.ErrMessage to pkg/errno/errname.go,
• moves the function mysql.Message to pkg/errno/errname.go,
• adds any missing error codes from pkg/parser/mysql/errcode.go to pkg/errno/errcode.go,
• updates all references to error codes defined in pkg/parser/mysql/errcode.go to the versions defined in pkg/errno/errcode.go,
• removes the file pkg/parser/mysql/errcode.go,
• adds any missing error messages from pkg/parser/mysql/errname.go to pkg/errno/errname.go,
• updates all references to the messages in pkg/parser/mysql/errname.go to the versions in pkg/errno/errname.go,
• removes the file pkg/parser/mysql/errname.go,

The error messages in both the mysql package and errno were compared to insure compatibility.
