Optimize the Parcel read/write of common window data

The Parcel read/write speed of MergedConfiguration/InsetsSource
becomes 4x+ faster.

Because writeParcelable sends additional type info which is
unnecessary if the type is known on the reading side, replace
the usages to writeTypedObject and well-written readFromParcel.
That saves the time of class lookup and object creation.
