why are we using null here for the Environment? In L:71 a new StandardEnvironment is passed on.

can't we put this in one stream processing instead of running over parameters twice?

Should we add variables for a given SimpleEvaluationContext as well?

Introduce ValueExpressionQueryRewriter as replacement for SpelQueryContext and QueryMethodValueEvaluationContextAccessor to encapsulate common ValueExpression functionality for Spring Data modules wanting to resolve Value Expressions in query methods. Reduce dependencies in RepositoryFactoryBeanSupport and RepositoryFactorySupport to EvaluationContextProvider instead of QueryMethodEvaluationContextProvider to simplify dependencies. Deprecate QueryMethodEvaluationContextProvider and its reactive variant for future removal. Closes #3049
