PHP: PSR-1 asks for constants to be all upper case

Is your feature request related to a problem? Please describe

This should not be valid PHP code as the class constant Permissions is not upper case.

final class TablePermissionElement extends AbstractFormElement
{
    private const Permissions = [];
}

Describe the solution you'd like

Maybe a PHP CS Fixer rule can be implemented to fix it to:

final class TablePermissionElement extends AbstractFormElement
{
    private const PERMISSIONS = [];
}

Additional context

There are no hard rules but TYPO3 follows coding standards.

PSR-1: Basic Coding Standard

• Class constants MUST be declared in all upper case with underscore separators.

TYPO3 coding standards

https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/CodingGuidelines/CglPhp/GeneralRequirementsForPhpFiles.html#typo3-coding-standards

The package TYPO3 Coding Standards provides the most up-to-date recommendation for using and enforcing common coding guidelines, which are continuously improved. The package also offers toolchain configuration for automatically adjusting code to these standards. Specifically, a PHP CS Fixer configuration is provided, that is based on PER-CS1.0 (PSR-12) at the time of this writing, and transitioning towards PER-CS2.0.

2.1 Basic Coding Standard

Code MUST follow all rules outlined in PSR-1.
