/**
* Parses a message payload using the provided schema and error processor to handle validation.
* The function attempts to parse the message payload based on the provided schema.
* If successful, it returns a success object containing the parsed message along with the original message.
* If an error occurs during parsing, it returns an error object processed by the error processor.
*
* In success case, it returns original and parsed messages because zod is cutting off additional fields that are not
* defined in the schema, and we might add extra fields on publish to be used on the consumer side.
* eg: timestamp to avoid infinite retries on the same message.
*
* @param messagePayload The message payload to be parsed.
* @param schema The Zod schema used for parsing the message payload.
* @param errorProcessor An error resolver function used to process any validation errors encountered during parsing.
*
* @returns Either an object indicating a successful parsing result or an error encountered during parsing.
