Improve restore sanitization - Fixes [sc-24840]

[uberbrady]

Some older version of MySQL dump INSERT statements as:

INSERT INTO `blah` VALUES
(blah,blah,blah),
(blah,blah,blah),
(blah,blah,blah);

And we were unable to parse that.

Additionally, while MySQL can easily handle \r\n or \n line-endings, our regex validator was getting confused by \r\n, so now we trim them off and normalize them to just \n.

Also, since I was debugging the SQL sanitizer, I re-added back in a --sql-stdout-only command-line option that only sanitizes the SQL and dumps the result to STDOUT - which should make this easier to debug in the future.

PR Summary

• Implementation of newline character update
  The parse_sql method in RestoreFromBackup.php has been improved with an incorporated new format for its text output. This reformatting includes appending a newline character at the end of method lines, aiding overall readability.

• Removal of newline character
  Contrastingly, a newline character previously present at the end of method lines has been removed. This adjustment helps to maintain optimal formatting, eliminating any additional spaces that might not be necessary.

• Addition of new command line flag
  The handle method in RestoreFromBackup.php has been updated with a --sql-stdout-only flag. This addition enhances the script's functionality by offering users a new command line option to increase flexibility when performing operation with the script.
