Revert "cleanup: Simplify usage of MinIOSourceProxyRequest (#19553)" 

This reverts commit 928c0181bf.

This change was not correct, reverting.

We track 3 states with the ProxyRequest header - if replication process wants
to know if object is already replicated with a HEAD, it shouldn't proxy back
