Revert "Refactor CopyAttributeOut{CSV,Text}() to use a callback in COPY TO"
This reverts commit 2889fd23be56, following a discussion with Andres
Freund as this callback, being called once per attribute when sending a
relation's row, can involve a lot of indirect function calls (more
attributes to deal with means more impact). The effects of a dispatch
at this level would become more visible when improving the per-row code
execution of COPY TO, impacting future potential performance
improvements.
