Manually manage memory of native objects

Even though these surfaces/transactions are unreachable, it still
takes time for the GC/NativeRegistry/FinalizerQueue to actually
flush/free references (even if you force GC, it won't flush the
NativeRegistry/FinalizerQueue). This skews the results of our
memory benchmark tests since they measure instantaneous memory.

So, add logic to manually release Transactions/SurfaceControls
when we know they won't be used. This is extra tricky due to
unparceling creating new refcounts. To resolve this, we assume
that all remotes are getting a COPY of all surfaces and then we
make deep-ish copies on the CALLER side if the binder is actually
local. We can't alter the logic on the receiver side because the
binders are one-way and thus PID information isn't available.
