Add binder transaction size tracing 

As binder transaction latency depends heavily on message size, it's
useful to trace the sizes as well.

I'll submit a change to catapult (systrace visualizer) to add the size
information to the binder transaction events as well.

Test: ran systrace.py ... binder_driver, looked at captured data
Test: mm in $ANDROID_BUILD_TOP
