Remove advisory registerNativeAllocation().

After consulting with the ART team, we learned that sending them
detailed advisory native allocation sizes isn't as useful when the
overall lifecycle of the object is tightly managed, which is the
case with Parcel objects.  (Because Parcel users use explicit
obtain() and recycle() methods, any variable-sized native
allocations have already been freed by the time a Parcel instance
is considered for GC.)

The Parcel benchmarks referenced below are showing a uniform ~3%
performance improvement across 1, 4, and 16 thread cases.  Note that
this is in addition to the improvements recently made with the shift
to a linked-list pooling design.
