[TASK] Remove unused properties from EditDocumentController

The values "_serialNumber", "_scrollPosition", "viewId_addParams"
are hidden form fields that are relics from TYPO3 Core v3.x,
long unused and obsolete.

Same goes for "uc" which just parks an incoming value (where
the FormEngineUtility::updateInlineView() can also be moved
inside the EditDocumentController), and unused values such as
"newC".
