Message:

Streams: Return early from wp_is_stream() for paths that aren't streams.

Some versions of PHP appear to have a memory leak that is occasionally triggered by calling stream_get_wrappers(). In order to avoid calling this, we can return early from wp_is_stream() when $path doesn't contain ://.

Props pbiron, JPry, dontstealmyfish.
Merges [43466] to the 4.9 branch.
Fixes #44532.
