What is the purpose of the change

适配Spring6.x 和 native-image

Brief changelog

适配Spring6

spring-context-support 里面的AbstractAnnotationBeanPostProcessor类继承的InstantiationAwareBeanPostProcessorAdapter类在spring 6.x已经被删除，在nacos-spring-context项目里新建AbstractAnnotationBeanPostProcessor类并改为实现InstantiationAwareBeanPostProcessor，涉及此类的都替换掉新建的AbstractAnnotationBeanPostProcessor

支持native-image

1. 首先新建nacos-spring-context-aot项目，该项目的作用是springboot插件的process-aot目标运行时扫描所有添加的bean，如果bean里使用了@NacosInjected注解或@NacosValue注解，就把注解标注的属性添加到reflect-config.json里面
2. 因为AOT运行时Spring不会调用ImportBeanDefinitionRegistrar的registerBeanDefinitions方法，所以将registerBeanDefinitions方法中除了注册BeanDefinition操作的其他操作放到EnableNacosAotProcessor里，EnableNacosDiscoveryAotProcessor和EnableNacosConfigAotProcessor同理
3. AOT运行时@NacosPropertySource注解标注的类的BeanDefinition是RootBeanDefinition，需要将这些RootBeanDefinition转换为AnnotatedGenericBeanDefinition

Verifying this change

适配Spring6

首先将https://nacos.io/zh-cn/docs/nacos-spring.html里的功能都debug测试一遍，debug时统计没有走到的代码，然后运行以下单元测试即可测试上述没有走到的代码：

• PropertiesPlaceholderResolverTest
• ObjectUtilsTest
• NacosUtilsTest
• ConfigParseUtilsTest
• NacosConfigLoaderTest
• DelegatingNamingServiceTest
• DelegatingNamingMaintainServiceTest
• DataBinderTest
• EventPublishingConfigServiceTest
• NacosPropertySourceXmlBeanDefinitionTest
• GlobalNacosPropertiesBeanDefinitionParserTest
• NacosValueAnnotationBeanPostProcessorTest
• NacosPropertySourceBuilderTest
• AbstractAnnotationBeanPostProcessorTest

  支持native-image

  新建一个项目，导入nacos-spring-context和nacos-spring-context-aot，开启GraalVM的Tracing Agent功能（运行java程序时添加参数：-agentlib:native-image-agent=config-output-dir=/path/to/config-dir/），将https://nacos.io/zh-cn/docs/nacos-spring.html里的功能测试一遍，之后将生成配置文件拷贝到META-INF/native-image下，再使用spring-boot-maven-plugin的process-aot和native-maven-plugin的compile功能，运行mvn clean package -Pnative即可生成可执行程序。 运行生成的可执行程序，再将https://nacos.io/zh-cn/docs/nacos-spring.html里的功能测试一遍，功能正常即测试通过

Follow this checklist to help us incorporate your contribution quickly and easily:

• [x] Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
• [x] Format the pull request title like [ISSUE #123] Fix UnknownException when host config not exist. Each commit in the pull request should have a meaningful subject line and body.
• [x] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• [x] Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add integration-test in test module.
• [ ] Run mvn -B clean package apache-rat:check findbugs:findbugs -Dmaven.test.skip=true to make sure basic checks pass. Run mvn clean install -DskipITs to make sure unit-test pass. Run mvn clean test-compile failsafe:integration-test to make sure integration-test pass.
