Stas Kelvich 069b5b0a06 Make postgres --wal-redo more embeddable. ...

* Stop allocating and maintaining 128MB hash table for last written

  LSN cache as it is not needed in wal-redo.

* Do not require access to the initialized data directory. That
  saves few dozens megabytes of empty but initialized data directory.
  Currently such directories do occupy about 10% of the disk space
  on the pageservers as most of tenants are empty.

* Move shmem-initialization code to the extension instead of postgres
