[REF] Ensure that Privacy (single checkbox) fields show up on Event R…

[seamuslee001]

…egistrations when fields are used in a profile

Overview

This modifies the UFFields templates to only handle Radios and Checkboxes fields here if the field is not type boolean. This seems to fix the problem @jmcclelland identified in this PR #30992.

Before

Checkboxes don't show up when privacy fields included on event registrations

After

Checkboxes for privacy fields show up correctly

@seamuslee001 .entityType.php files do not support proprietary quickform elements like "advcheckbox". The translation from standard element types (CheckBox) to quickform-specific types (advcheckbox) should be done in the form layer.

@colemanw ok I think i have it sorted correctly now then I think the UFGroup code was correctly adding advcheckboxes here but the template was being a bit silly
