fix(ivy): attached flag not being reset when view is destroyed (#29064)

Currently we only reset the `Attached` flag of a view if it is detached through its parent, however this means that if a root view is destroyed, its flag will never be reset. This manifested itself in one of the Material tests where we were destroying the root view.

This PR resolves FW-1130.
