* otelctx: Only decode the traceparent and tracestate headers

We all change the UnicodeDecodeError exception to be a debug message.
This really shouldn't happen oncee we are restricting the headers to
tracestate and traceparent though.

* tracing: Inject legacy headers into tracing context as well.

* Move W3C header list to top-level constant

* Emit debug-level log for UnicodeDecodeError
