In order to make TCA slimmer and more understandable, the
`required` configuration is now used in favor of
`eval`, which is also enforced by an automatic
TCA migration.

At least since #67354 TYPO3 is able to use an explicit `required`
configuration:

    'column' => [
        'label' => 'foo',
        'config' => [
            'type' => 'input',
            'required' => true,
        ],
    ]

Resolves: #97035
