Enhancement: Sniffer additions

[dereuromark]

I recommend adding/porting a few snippets from the current leading collection of sane sniffs^^

• https://github.com/php-collective/code-sniffer/blob/master/PhpCollective/Sniffs/PHP/RemoveFunctionAliasSniff.php ( refs https://github.com/cakephp/cakephp/pull/17864#discussion_r1728959307 )

as well as a few other useful ones.

Removing function aliases seems like a good addition.
