smgr_* Functions, including smgr_AORelOpenSegFile, were added to CDBD in order to support compute/storage separation solutions, optimized for append load (in few words, for https://github.com/yezzey-gp/yezzey to work). Yezzey uses current segment file relation OIDs in its internal logic. It is not necessary to pass OID each time we call smgr_AORelOpenSegFile, because extension can perform syscahe lookup.
A ratio for this change is to save few CPU cycles where possible.
