feat(config): #13299 Enhance spring boot configuration metadata

[oxsean]

What is the purpose of the change

See #13299
Enhance spring boot configuration metadata

Brief changelog

1. Enhance comments in relevant configuration classes by ChatGPT.
2. Create the module dubbo-spring-boot-configuration-metadata-compatible for generating metadata.
3. Adjust dubbo-spring-boot-autoconfigure-compatible to using the generated spring-configuration-metadata.json.

Why

Configuration beans of dubbo are located in the dubbo-common module, and it's not suitable to add spring boot dependencies.
However, spring configuration metadata generation relies on read javadoc from the source code and cannot use the @NestedConfigurationProperty annotation.
This leads to missing comments and a lack of nested configuration options. Therefore, we use an independent module to copy the code and generate metadata.
