Support for HTTP GET map parameters

[kwondh5217]

Motivation:

This pull request addresses #6058

Currently, @Param cannot be mapped to a Map, but this change enables that functionality, allowing query parameters to be handled as a Map.

Modifications:

• Introduced logic in AnnotatedValueResolver to detect when a parameter is of type Map and the @Param annotation has an unspecified value.
  • Future enhancements may include supporting the mapping of specific values to a Map when the @Param value is explicitly specified.
• Added a new method ofQueryParamMap to handle the creation of an AnnotatedValueResolver for mapping all query parameters into a Map.
  • Query parameters are collected into a Map using the stream-based collector.
• Updated the existing logic to ensure this behavior only applies when the @Param value is unspecified and the parameter type is Map.

Result:

• Closes Support for HTTP GET map parameters? #6058
• Users can now define a method parameter annotated with @Param as Map<String, Object> to handle all query parameters.

HI, @kwondh5217, thanks for the PR. 😉
Would you add an e2e test that verifies if this change works?

GET http://127.0.0.1:xxx/map?a=b&c=d

@Get("/map")
public HttpResponse map(@Params Map<String, Object> map) {...}

@minwoox Thanks for your comment!
I've added a test in AnnotatedServiceTest to verify that this change works.
Please take a look when you have time! 🙇
