fix: payload schema reference resolution

[VisualBean]

About the PR

Dependency resolution is now enforced during writing depending on the writer settings.
Before you had to specifically call "ResolveReferences()".

This enables a slightly easier usecase, where you can create an object model of references, and still get a document out that matches the writer settings.

Payload has been added as a "Reference" type, as it should have been all along.

Payload sub references, now resolve correctly as well.

Using default setting (ReferenceInlineSetting.DoNotInlineReferences)
will yield the following output

channels:
  mychannel:
    publish:
      message:
        payload:
          type: object
          required:
            - testB
          properties:
            testC:
              $ref: '#/components/schemas/testC'
            testB:
              $ref: '#/components/schemas/testB'
components:
  schemas:
    testD:
      type: string
      format: uuid
    testC:
      type: object
      properties:
        testD:
          $ref: '#/components/schemas/testD'
    testB:
      type: boolean

Where setting ReferenceInlineSetting.InlineReferences
Will now correctly resolve references from components

        payload:
          type: object
          required:
            - testB
          properties:
            testC:
              type: object
              properties:
                testD:
                  type: string
                  format: uuid
            testB:
              type: boolean
              description: test
