[TASK] Various cleanups regarding comments and API calls

This patch is a small summary of clean ups in various
places of TYPO3 Core.

- EditDocumentController can be simplified to retrieve the closeUrl()
- Comment adaptions in GeneralUtility
- Comment adaptions and code simplification in ContentObjectRenderer
- HMENU debug option can be fetched from TSFE TypoScript directly
- TypoLinkBuilder can use "TSFE->initTemplate()" directly
  to instantiate the TemplateService, and should hand over
  proper values in the constructor.
