[Server][Client] Bridge W3C trace context between HTTP headers and _meta (SEP-414) (#473)

Browse source 
RequestMeta::parseTraceContext() now falls back to the native traceparent/
tracestate/baggage HTTP headers when _meta carries none, and HeaderFactory
mirrors an application-set _meta trace context onto those same headers on
outbound requests. _meta wins when both are present.
