Ruleset: add a few extra sniffs + a property for one of the PSR12 sniffs

* The `PSR12.ControlStructures.BooleanOperatorPlacement` sniffs checks for consistent placement of boolean operators in control structure conditions.
    The extra property enforces that these are always placed at the start of a line.
* PSR12 has no opinion on array formatting. The `Generic.Arrays.ArrayIndent` sniff will at least safeguard some semblance of normalized arrays.
* The `Generic.CodeAnalysis.EmptyPHPStatement` prevents empty PHP statements, like when there is a duplicate semi-colon at the end of a statement.
* The `Generic.ControlStructures.DisallowYodaConditions` ensures that conditions never use Yoda.
* Additionally, the `Generic.CodeAnalysis.ForLoopShouldBeWhileLoop`, `Generic.CodeAnalysis.JumbledIncrementer`, `Generic.CodeAnalysis.UnconditionalIfStatement`, `Generic.CodeAnalysis.UnnecessaryFinalModifier`, `Generic.PHP.ForbiddenFunctions` and the `Squiz.WhiteSpace.SemicolonSpacing` sniffs, which were already in use in the PHP Parallel Lint repo, but not in the other repos, have also been added.
    Note: the `Generic.PHP.DeprecatedFunctions` sniff, as used in the PHP Parallel Lint repo, has **not** been added as the PHPCompatibility standard included a far more comprehensive and stable sniff for the same.
