- Added new trace events to track the ReOpenFile API. Updated the PlatformFileTraceAnalysis to process the respective new trace events. This fixes the issue where activities were displayed in Unreal Insights as I/O events with "Unknown" file (UE-114506).
- Updated warning messages and debug code in PlatformFileTraceAnalysis.
- Added handle tracking in Insights for I/O Activity events. File handle and read/write handles are now displayed in tooltip of an I/O Activity event.
- Added "ReOpen" as a separate I/O activity type.

- Added wp.Runtime.ToggleDrawRuntimeCellsDetails : Lists all world partition runtime streaming cells with their name and grouped by streaming state
- Added world partition debug filters (by datalayer(s), streaming status, grid name(s), cell name(s)) that affects debug display (runtime hash 2d/3d, cell details)
- Added Data Layer streaming status in 2d/3d runtime hash debug draw
- Added Legends with colors and minimal stats for DataLayers and Runtime Streaming Status

- Implement ability to unset metadata values by setting with nullptr
- Sanitize metadata to remove commas from values and keys (the commandline is excluded because it's special)
- Set a starttimestamp metadata value (in seconds since the Unix epoch).
- Add metadata for OS, CPU, Namedevents (at capture start)
- Log metadata changes

Avoid activating any external profiler by default as this could cause slowdown depending on which profiler gets randomly activated

In a previous change TraceAux::Initialize was moved to a point very early in process lifetime. At this point the config system is not ready, so resolving data driven channel presets does not work. To solve this we make two changes, define two presets in code (default and memory) which require very early application, and add a second pass of channel initialization which is executed directly after config system is up.

1) TlsAutoCleanup: in the previous version `FTlsAutoCleanup` used `FRunnableThread` to store registered instances and to delete them on `FRunnableThread` destruction. This means that all threads that are not created by `FRunnableThread` (the game thread in particular, and all 3rd-party threads) never delete registered `FTlsAutoCleanup` instances. This change moves the storage from `FRunnableThread` to TLS to cover all threads
Thsi change can break systems that implemented a workaround for this problem, e.g. by manually deleting registered `FTlsAutoCleanup` instances on the game thread exit, as now this instances will be deleted twice. The solution is to remove the workaround and to rely on uniform `FTlsAutoCleanup` behaviour on all threads.
#rb steve.robb
2) removed CpuProfilerTrace workaround to handle the fact that FTlsAutoCleanup leaks on the game thread, as this is fixed by (1).

Add function to query if the static API is init and thread should be running
Tidy up some direct checks to the init count to use the new IsRunning function
Make init reference count signed and check for it going negative (mismatched startup/shutdown calls)
Disclaimer: init reference count isn't really used yet, but I'm hoping to propose using it more broadly in the future

Add support for detectors that are constructed outside of when the StallDetector system is started up.
This gives us the flexibility to startup and shutdown within a finer scope of process startup and shutdown coming in a future change.

This adds some scalar statistics to the session summary:
* The total stall trigger count
* The total reported stalls
* The top stall name
* The top stall budget time in seconds
* The top stall cumulative overage time in seconds
* The top stall trigger count

This code is meant to help locate and send reports/telemetry for slow code pathways that create unresponsive conditions
FGameThreadHitchHeartBeatThreaded was considered, but doesn't fit Editor's needs because its designed around general GameThread deadlines
Editor workloads are much less homogenous, and proper async support for a consistent GameThread deadline in Editor is a ways away
This necessitates a more focused approach where we can instrument specific routines such that each issue their own telemetry report
Add a "Stalls" counter in the Frame Rate and Memory title bar stats
Add LogStall Log category for viewing details about stalls that have occurred
Introduces a stall counter object on the GameThread to collect statistical data about stalls (this will not report to telemetry)
Future changes will introduce report objects into specific routines to upload to crashreporter
Future changes will introduce support for non-Windows OSes
