service: Add GetTraceStats() to consumer endpoint
The new API allows a consumer to obtain trace and buffer stats about the
current tracing session separately from the actual trace data. Consumers
may use this to show stats such as buffer utilization in a UI.
Also adds a few new stats to TraceBuffer.
