Add options to enable and disable checksums in pg_checksums

Browse Source 
An offline cluster can now work with more modes in pg_checksums:
- --enable enables checksums in a cluster, updating all blocks with a
correct checksum, and updating the control file at the end.
- --disable disables checksums in a cluster, updating only the control
file.
- --check is an extra option able to verify checksums for a cluster, and
the default used if no mode is specified.

When running --enable or --disable, the data folder gets fsync'd for
durability, and then it is followed by a control file update and flush
to keep the operation consistent should the tool be interrupted, killed
or the host unplugged.  If no mode is specified in the options, then
--check is used for compatibility with older versions of pg_checksums
(named pg_verify_checksums in v11 where it was introduced).
