In order to avoid scopes ending up after thread end (rare) clear the thread buffer pointer. In that case a new thread buffer will created, specifically for that scope.

[CL 18688595 by johan berg in ue5-main branch]
Trace normally runs with a worker thread to write data regularly, however when `FPlatformProcess:SupportsMultithreading` was false we did not start the worker thread, instead we relied on EndFrame delegate to manually pump Trace. When tracing is very intense (e.g. memory tracing) could lead to data building up internally, up to 1 GB of data by the time the first frame callback came. We have recently added a special sync type packet in the stream to deal with edge cases related to late-connect, so analysis stalled until those came trough. However since the backlog of data has to be transmitted first, those sync packet ended up after the initial data. Analysis had to (very inefficiently) get trough that 1Gb of data before the first sync packet came through and events starts to appear.
With this change trace always start the worker thread (if we're intending to fork) regardless of the SupportsMultithreading setting.

When starting a trace to a file, all relative paths should go to the Profiling directory, on Windows even paths that starts with '/'. Also cleaned up includes.

* An extra '&' token was removed on the type alias in the no logging case.
* In the case where trace is enabled, but logging is disabled, made a identical solution in TraceAuxImpl.

In order to be able to output detailed error and status messages to both core log or console feedback log depending on situation, add argument to set the target category. Also removed now redundant logs in console commands, since more detailed information is now emitted on the console feedback.

Append the default file name when the trace target path ends with a slash, for examplethe path "foo/bar/". The target trace file will then be "foo/bar/defaultname.utrace". Note that "foo/bar" will still target "foo/bar.utrace".

* Whenever starting a trace command (from the api or console command), reset the current command line list of channels.
* Don't assume default channels should be enabled if none are given. For command line arguments this will still be the case, but not console commands or the API.
* Emit log message when auto connecting.

* Added 'Trace.Enable' and 'Trace.Disable' console commands to control channels.
* 'Trace.Start' is marked as deprecated in favor of Trace.File.
* For 'Trace.File' both arguments are now optional, and heuristic for detecting a file argument implemented.
* 'Trace.Stop' no longer disables channels.
* 'Trace.Pause/Resume' now keeps a list of the current active channels which will be restored. Logic for enabling channels has been separated from EnableChannels which is used in initialization sequence.
* Changed FChannel toggling to directly write the state. This change was done to reduce confusion around enabling/disabling channels and preset that overlaps.
* Refactored some methods internal to FTraceAuxilliaryImpl

Refactor csvExecCmds to move the initialization logic into the CSV profiler itself. The execution still needs to happen in the engine, but this is now done during normal frame processing.
Fix a bug when processing csv execcmds with colons, e.g file paths

* TraceMalloc should not use it's own root heap. Instead it will use a regular heap in system memory and make fake heaps (since we can't track virtual allocations for trace's own allocations).
* The first named was miscategorized as a root heap.
