Remove IsSynchronous API from NavigationHandle.

The IsSynchronous API on NavigationHandle is almost identical to
IsSamePage and there is no reason for the two to exist. Also, IsSamePage
can be based on the same implementation as IsSynchronous, which allows
it to be called at any point in the lifetime of NavigationHandle.
