Make max length of SpEL expressions in an ApplicationContext configurable

Browse Source 
This commit introduces support for a Spring property named
`spring.context.expression.maxLength`. When set, the value of that
property is used internally in StandardBeanExpressionResolver to
configure the SpelParserConfiguration used when evaluating String
values in bean definitions, @⁠Value, etc.

Closes gh-31952
