Prior to this commit, the Micrometer instrumentation support would auto-configure a `ServerHttpObservationFilter` for creating observations in Spring MVC applications. As of Spring Framework 6.2, applications can extend this filter class to get notified of the observation scope being opened. This commit contributes a new `TraceHeaderObservationFilter` implementation that writes the current Trace Id (if present) to the `X-Trace-Id` HTTP response header. This feature is disabled by default, applications will need to enable `management.observations.http.server.requests.write-trace-header`. ` Closes gh-40857
