Add support to configure adding jackson @JsonPOJOBuilder annotations to generated builders

[maff]

Adds a new option structure to instruct record-builder to add a Jackson @JsonPOJOBuilder annotation to the generated builder. While this implements library-specifics, it does not add Jackson as dependency (only on the test module).

Example usage:

Auto-detect Jackson version (default)

@RecordBuilder.Options(jackson = @RecordBuilder.JacksonConfig(jsonPOJOBuilder = true))

Explicitly add Jackson 2.x annotation (fail if J2 is not available):

@RecordBuilder.Options(
    jackson = @RecordBuilder.JacksonConfig(
        jsonPOJOBuilder = true,
        version = JacksonVersion.JACKSON_2
    )
)

With custom setter prefix:

@RecordBuilder.Options(
    jackson = @RecordBuilder.JacksonConfig(jsonPOJOBuilder = true),
    setterPrefix = "set"
)

Closes #229

@Randgalt any feedback on this approach? I would be great to have this as an option for projects relying on Jackson and still wanting to benefit from RecordBuilder's initialization & defaults logic.

I'm afraid it's not that simple. Recently, Jackson 3 was released with changed package names. Is it possible to check what annotations are presented on the classpath and add appropriate annotation here?

@Randgalt @semyon-levin-workato Updated to support both Jackson 2 and 3 by detecting available classes on the classpath, with support to specify a specific version in case both versions are present.

Would be awesome if we could progress with this feature for better out-of-the-box Jackson compatibility.
