Spring Add the ability to limit ContentCachingResponseWrapper cache size

It would be nice if ContentCachingResponseWrapper could support setting a limit to its cache so that response body is cached only up to this limit. This could be beneficial for the existing ShallowEtagHeaderFilter and other use case that leverage ContentCachingResponseWrapper.

See https://github.com/spring-projects/spring-boot/pull/43697#issuecomment-2811474524 and the discussion around it for background of this enhancement request.
