Reland: "traced: Add TraceWriter stats""

This reverts commit 2e957872bbcb9933e56bf33615bb14225ae6a2a5.

New change:
fixed an integration tests that was statically allocating a 1K
buffer on the stack and reading into that. That caused a truncated
trace that failed to parse because of the extra data being appended
in the new tracewriter stats.

Original CL description:
>    Keep track of chunk usage in TraceBuffer,
>    broken down by sequence id (i.e. by writer).
>    This is to later debug poor usage of the trace
>    buffer, which affects some long traces (see bug).
