Add Jackson 3 support

[jiholee17]

Closes #899

This PR re-introduces support for Jackson 3 (now configured by default in Spring Boot 4 projects) by detecting which versions of Jackson annotations are available on the compile classpath and adding annotations for the available version(s). If neither version is found, codegen defaults to Jackson 2 annotations for backwards compatibility. If both versions are found, codegen adds both annotations and defers to runtime selection behavior.

Affected annotations are:

• @JsonDeserialize in com.fasterxml.jackson.databind.annotation (Jackson 2) and tools.jackson.databind.annotation (Jackson 3)
• @JsonPOJOBuilder in com.fasterxml.jackson.databind.annotation (Jackson 2) and tools.jackson.databind.annotation (Jackson 3)

Example with both Jackson versions:

import com.fasterxml.jackson.databind.`annotation`.JsonDeserialize as FasterxmlJacksonDatabindAnnotationJsonDeserialize
import tools.jackson.databind.`annotation`.JsonDeserialize as ToolsJacksonDatabindAnnotationJsonDeserialize
...
@JsonTypeInfo(use = JsonTypeInfo.Id.NONE)
@FasterxmlJacksonDatabindAnnotationJsonDeserialize(builder = Country.Builder::class)
@ToolsJacksonDatabindAnnotationJsonDeserialize(builder = Country.Builder::class)
public class Country(
...

Example with single Jackson version:

import com.fasterxml.jackson.databind.`annotation`.JsonDeserialize
...
@JsonTypeInfo(use = JsonTypeInfo.Id.NONE)
@JsonDeserialize(builder = Query.Builder::class)
public class Query(
