ANDROID: Add dmabuf RSS trace event 



Dmabuf RSS is associated with a task, or group of tasks sharing the same
mm_struct and files_struct. Any time the RSS counter is modified for a
task, or group of tasks, emit a trace event with the current value of
the dmabuf RSS counter.

This allows for fast tracking of per-process dmabuf RSS by userspace
analysis tools like Perfetto, compared to periodically obtaining
per-process dmabuf RSS from procfs.
