win-capture: Fix hook collisions with multiple game captures

Before this change, after a game capture source would send a signal to
init or restart a graphics hook, it would respond to any and all hook
ready signals.

With multiple game capture sources in the same scene, a source could
receive the signal intended for another source, and show the wrong
texture.

This change adds the window handle to the name for shared data with the
hook, resulting in hooks for other sources being ignored.
