refactor(php-shim): give parse_url a typed UrlComponents result

parse_url now returns Option<UrlComponents> instead of a PhpMixed array,
and the component-selecting overload with the PHP_URL_* constants is gone:
callers read the field they want. Two call sites change behaviour as a
result, both towards PHP:

* CurlDownloader::handle_redirect tested scheme and host with is_null(), so
  an unparsable Location header (PhpMixed::Bool(false)) counted as an
  absolute URL. PHP's truthiness test sends it to the relative-path branch.
* Url::get_origin appended a literal port 0, which PHP treats as falsy and
  leaves off.
