[GenAI] Fix 11815: Modifications on AbstractInitializableBeanDefinition.resolveBean

[Jarvx]

Issue: #11815

Bug description

When a bean is conditionally disabled by throwing a DisabledBeanException from a factory method, other beans that @require the disabled bean should also be considered unavailable.

Root Cause & Solutions

The test reproduces the reported issue: a factory method throws DisabledBeanException to disable a bean, and another bean annotated with @Requires(bean = MyBean.class) should therefore not be created.

In the original code, the DisabledBeanException thrown during dependency resolution was wrapped in a DependencyInjectionException, causing ctx.findBean(AnotherBean) to throw instead of returning an empty Optional, and the test failed as shown in the logs.

The patch modifies AbstractInitializableBeanDefinition.resolveBean to rethrow DisabledBeanException directly (except for the special EachBean case which remains a DisabledBeanException), instead of wrapping it in DependencyInjectionException. This allows the upstream context to recognize the disabled dependency and honor @requires, resulting in findBean returning an empty Optional and the test passing.

Steps to reproduce

Please use this command to execute the provided test:

./gradlew :test-suite-kotlin-ksp:test
