fix: crash with creating OffScreenWebContentsView (#42920)

On the Mac platform, OffScreenWebContentsView uses Automatic Reference
Counting (ARC) to handle the lifecycle of offScreenView_. However, this
private member variable is not initialized and its value is undefined.
In some cases, it is initialized to a garbage value, which may cause ARC
to release the value incorrectly, resulting in a crash.
