Integrate `codecs::Encoder` with sinks

[binarylogic]

Like #9404 but for encoding/sinks

Issues that will be resolved with the integration:

• Add encoding.delimiter setting for socket sink #3454

Native encoding issues:

• Issues with parsing encoding configurations that prevent the user from specifying that there should be no framing (see review comments on enhancement(socket sink): Integrate encoding::Encoder with socket sink #10684)
• Sinks with configurable codecs should have input types related to the configured codec #12135
• Default framing based on encoding #12134

Other issues:

• Add sink octet framing that matches source octet framing #12434
• docs(codecs, sinks): Document changes to sink encoding #13331

• datadog_events
• datadog_logs
• datadog_traces
• aws_s3
