Support stream wrappers in stream_resolve_include_path()

[nikic]

php_resolve_path() / stream_resolve_include_path() are supposed to return the path that will be included by include -- for stream wrappers that should just be a no-op (if the file exists).

This also makes opcache_invalidate() work and solves the issue in #4392. Does anyone see an issue with doing this?

Looks like php_stream_open_wrapper may also use php_resolve_path and that use assumes that it returns NULL for stream wrappers...

I think there's some subtleties here that I'm not really familiar with, not going to pursue this.

What about only allowing resolving for file:// and phar://? That would cover most common use cases.
