[php-src] PR #23051: Zend: remove zend_parse_parameter()

Pull Request: https://github.com/php/php-src/pull/23051 Author: Girgias This API is far worse than just using the existing zend_parse_arg_TYPE() APIs. A SourceGraph search [1] shows this API is effectively only used by ext/ds to which a PR migrating away from this API has been submitted. [2] The other two usages are from a now deprecated extension [3] and @arnauld-lb's now longer maintained php-go project. [4] As such we think it is reasonable to remove said API.
