[!!!][FEATURE] Add PSR-14 Event and DTO for modifying resolved ImageResource

This replaces the previously available hook
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_content.php']['getImgResource']
which is therefore now removed.

The hook required implementations to implement
the `ContentObjectGetImageResourceHookInterface`,
which is now deprecated as it's unused due to
the hook removal.
