• [JsonEncoder][Serializer] Introducing the component #51718

The FrameworkBundle part of the JsonEncoder component introduction.

The component related config is quite simple:

framework:
    json_encoder:
        paths:
            App\EncodableDto\: '../src/EncodableDto/*'

Plus, the framework integration proposes the following bindings:

• EncoderInterface $jsonEncoder to the json_encoder.encoder service
• DecoderInterface $jsonDecoder to the json_encoder.decoder service

As this PR is based on top of #51718, only the last commit should be considered.
