Move system identifier generation to a common helper
The code used to generate a new system identifier is duplicated in multiple locations, including BootStrapXLOG(), pg_createsubscriber and pg_resetwal. Move the implementation to a common GenerateSystemIdentifier() helper and update existing callers to use it. This allows both backend and frontend code to share a single implementation of the system identifier generation algorithm.
