Breaking: #88667 - Removed additionalJavaScriptSubmit from FormEngine 

See forge#88667

Description 

FormEngine had the feature to add additional submit handlers via the option additionalJavaScriptSubmit , that can be set by form element renderables. TYPO3 uses RequireJS and a rewritten FormEngine since version 7, the property additionalJavaScriptSubmit has been removed.

Additional, functions of TBE_EDITOR that are associated with that feature (namely addActionChecks ) were removed as well.

Impact 

The option has no effect anymore, the code won't get executed at all.

Affected Installations 

All 3rd-party extensions using this option are affected.

Migration 

It is possible to create and register an AMD module.
