[!!!][FEATURE] Add PSR-14 Events for modifying inline element controls

This introduces two new PSR-14 events, enabling
extension authors to modify the enabled controls as
well as the corresponding controls' markup for
FormEngine inline elements.

This replaces the previously available hook
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tceforms_inline.php']['tceformsInlineHook']
which is therefore now removed.

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

Resolves: #97231
