Rename pg_verify_checksums to pg_checksums

The current tool name is too restrictive and focuses only on verifying
checksums.  As more options to control checksums for an offline cluster
are planned to be added, switch to a more generic name.  Documentation
as well as all past references to the tool are updated.
