Fields with no schema defined have no columns.

Merge request that replaces getSchema() with getPropertyDefinitions(). This fix now allows validation rules against url aliases :)

Here's a patch file if anyone wants to test out.

Bumping this to major as some fields cannot even be configured as the column field is based on schema declaration. The core path field for example has empty schema: https://git.drupalcode.org/project/drupal/-/blob/11.x/core/modules/path/....

The patch will fetch non-computed properties instead which allows us to add validations to the Url Alias form field. This is useful with regex patterns to restrict user entered paths.

The patch looks good, I try to merge it, but failed.
