- When CRC runs out of process, instead of reading the current thread context of the crashed thread, read and use the crash context that was reported during the crash (which is different).
- Added an optional context parameter to FGenericPlatformStackWalk::CaptureThreadStackBackTrace(), implemented it across all platforms, but only used on Windows.
On Windows, fixed InitStackWalking() and InitStackWalkingForProcess() to reset the process that needs to be walked.
- CRC, running out of process may run its own process or the Editor process and which ever was walking first ruled out the other.

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

- Count number of crashes before Analytics get initialized and report them as DelayedCrashCount field of the Editor summary session event.

- Prevented CrashReportClient from serializing the CrashContext to the memory buffer if it was already serialized once.
- Increased the default space reserved by memory buffer used to serialize the crash context from 32K to 128K because serializing the crash context of 'debug crash' command line in Editor uses up to 112K.
- Cleared the memory buffer before serializing the CrashContext in case it was serialized more than once preventing the internal buffer to grow needlessly. Also, the XML reader being limited, would only read the first one written, ignoring further and more recent ones appended.

- Fixed the application title, getting it from the engine version rather than hardcoding it.

- Implemented a special logger inside CrashReportClientEditor to capture and save important events such as crash reporting (along with the CrashGUID)
- When CrashReportClientEditor sends all the Editor summary events, if an error was detected in the session being sent, the mini-log for that session is attached to the analytic event.

- Added code to the Editor to detect and report when CrashReportClientEditor exited unexpectedly. (MonitorExceptCode 777005 is set in the Editor session summary event)
- Added a retrial loop to CrashReportClientApp to retry opening the the handle on the Editor process if the first time fails.
