Expose sequence page LSN via pg_get_sequence_data. This patch enhances the pg_get_sequence_data function to include the page-level LSN (Log Sequence Number) of the sequence. This additional metadata will be used by upcoming patches to support synchronization of sequences during logical replication.
By exposing the LSN, we enable more accurate tracking of sequence changes, which is essential for maintaining consistency across replicated nodes.
