Fix build with fmt 8/9

+ changes in segment_manager.cc and segment_manager.h are backported from
  part of the large changes in https://github.com/ceph/ceph/commit/d5b0cd13
+ change in node_extent_accessor.h is not forwarded to upstream since it's
  a workaround. However it doesn't harm since it's just a error message
  which shouldn't happen anyway.
+ changes in seastar is backported from
  https://github.com/scylladb/seastar/commit/dfb62861
+ changes in crimson/osd/main.cc is backported from
  https://github.com/ceph/ceph/commit/58cb9bac
