/**
 * Adds a parser to the metadata of the specified target. This function first retrieves all existing parsers,
 * filters them based on certain conditions, and then appends the new parser to the metadata.
 *
 * @param {ElementParser} parser - The parser instance to be added. This parser should have a `parse` method and a `propertyKey`.
 * @param {any} target - The target object to which the parser will be added. This is typically a class or a class instance.
 *
 * The function operates in two main steps:
 * 1. It retrieves all element parsers associated with the constructor of the target, filters out any existing parsers that
 * should not be overwritten, and then adds the new parser's `parse` method to the `ElementParserMetaData.PARSER` metadata key.
 * 2. It retrieves all element parser instances associated with the constructor of the target, filters out any existing parser
 * instances that have the same `propertyKey` as the new parser, and then adds the new parser instance to the
 * `ElementParserMetaData.PARSER_INSTANCE` metadata key.
 *
 * Note: The function currently does not handle overwriting existing parsers with the same `propertyKey`. This functionality
 * needs to be tested and potentially implemented.
