libbinder_ndk: align parcel_utils and parcel order

The general order of binder_parcel.h is:
Helper types, Binder, BarcelFileDescriptor, Status, String, Primitives

And within each of these sections is first the bare type and then
the array type.

Since I will be adding more utility functions shortly, I am re-ordering
binder_parcel_utils.h so that it matches the binder_parcel.h file.
