Subject: [PATCH] SecurityEvaluationContextExtension Signature

SecurityEvaluationContextExtension.getRootObject() should have a signature
with a return type of SecurityExpressionRoot. See
EvaluationContextExtension javadoc
https://github.com/spring-projects/spring-data-commons/blob/eed7658ce54dfc3960c28cd90f551fdd27b4adba/src/main/java/org/springframework/data/spel/spi/EvaluationContextExtension.java#L61-L64

This enhancement will allow for Spring Data to make certain types of
optimizations.

Fixes gh-7891
