fix: bind offscreen paint callback to child WebContents
Previously, MaybeOverrideCreateParamsForNewWindow bound the
OffScreenWebContentsView's paint callback to the parent WebContents
using base::Unretained(this). This was both unsafe (dangling pointer
risk if the parent is destroyed before the child) and semantically
incorrect — paint events belong to the child window, not the opener.
Replace the callback in MaybeOverrideCreateParamsForNewWindow with
base::DoNothing(), then rebind it to the child WebContents in
AddNewContents via a new SetCallback method on OffScreenWebContentsView.
