[!!!][TASK] Remove TYPO3.jQuery

This change removes the availability of TYPO3.jQuery within the
TYPO3 Core by default.

The constants PageRenderer::JQUERY_NAMESPACE_DEFAULT / and
PageRenderer: JQUERY_NAMESPACE_DEFAULT_NOCONFLICT namespace options
"jQuery" are removed. This also means the removal
of having custom namespaces of jQuery (e.g. TYPO3.bennis_jQuery) leaving
"noConflict" to be used by default.
