[!!!][FEATURE] Add PSR-14 ModifyImageManipulationPreviewUrlEvent

This introduces a new PSR-14 event, enabling
extension authors to modify the preview url within
the image manipulation element, used e.g. for the
`crop` field of `sys_file_reference`.

This replaces the previously available hook
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['Backend/Form/Element/ImageManipulationElement']['previewUrl']
which is therefore now removed.

Resolves: #97230
