Add tracing for dequeueBuffer, detachBuffer and cancelBuffer

The FrameTracer prototype currently doesn't have some of the events
traced. This change adds the plumbing required to emit dequeueBuffer,
detachBuffer and cancelBuffer. Only the dequeueBuffer is made to emit
the event in this CL while enabling detach and cancel to have a place if
emitting is required.

Test: Build and trace with GAPID and FrameTracer perfetto changes.
