[TASK] Use $ instead of TYPO3.jQuery

In TYPO3 6.0 we introduced TYPO3.jQuery as a possibility to have jQuery
run side-by-side with prototype.js in a no-conflict mode.

Since TYPO3 7.5, prototype.js was removed, and $ can be used.

PageRenderer now sets TYPO3.jQuery AND $ as shorthand-functionality
and all places in the TYPO3 Core are replaced with the common $
functionality, so TYPO3.jQuery should be avoided.
