Added trace to conhost to instrument buffers that are cooked prior to being passed to the console. * [x] I've discussed this with core contributors already (internal) VALIDATION - Ensured trace is correctly logged in ETL (via TraceLog)

Module Name:
|
|
- tracing.hpp
|
|
|
|
Abstract:
|
|
- This module is used for recording tracing/debugging information to the telemetry ETW channel
|
|
- The data is not automatically broadcast to telemetry backends as it does not set the TELEMETRY keyword.
|
|
- NOTE: Many functions in this file appear to be copy/pastes. This is because the TraceLog documentation warns
|
|
to not be "cute" in trying to reduce its macro usages with variables as it can cause unexpected behavior.
