[TASK] Use path access in EEL expressions

In order to work in protected eel contexts the EEL expression
for reading node properties should use path access instead of
calls to getter methods. This will allow the
TYPO3.TYPO3CR.Search to use the EelUtility from the EEL
package instead of own code.

Individual expressions for indexing should also be adapted to
use path access.
