[GIT-PULLS] [php-src] PR #22863: streams: php_stream_copy_to_stream_ex() drops progress notifications.

Fix #22841

The fd-level copy fast path hands the transfer to the kernel, so the bytes bypassed php_sockop_read() and neither the progress increments nor the completion event were emitted. Skip the fast path when either stream carries a context notifier.
