Squiz/ClassDeclaration: allow for function attributes

The `Squiz.Classes.ClassDeclaration` sniff checks the number of blank lines _after_ a class closing brace to be exactly one blank line.

To prevent conflicts with other sniffs checking blank lines before function declarations, it bows out when the next thing after the class declaration is a function declaration and defers to the function declaration sniff to handle the "blank lines before function" check.
See squizlabs/PHP_CodeSniffer 2033 for historic context.

However, the above "bowing out" breaks when a function after a class has PHP 8.0+ attributes attached to it and the sniff would still the `NewlinesAfterCloseBrace` error.

Fixed now.

Includes tests.

Note: the new "errors" caused by the new tests are for the `MultipleClasses` code, which is unrelated to this fix and valid.
