[!!!][FEATURE] Introduce PSR-14 ModifyRecordOverlayIconIdentifierEvent

This introduces a new PSR-14 event, enabling extension
authors to modify the overlay icon identifier of any
record icon.

This replaces the previously available hook
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['TYPO3\CMS\Core\Imaging\IconFactory']['overrideIconOverlay']
which is therefore now removed.

Resolves: #101603
