uri: Make php_uri_parser structs PHPAPI (php#20243)

This allows extensions that already know which parser to use and don't need the
generic lookup facility to directly refer to the desired parser without needing
to go through `php_uri_get_parser()` (which also requires allocating a
`zend_string*`).
