* Contains some selected back outs from other cls that included config context dependent changes, though it's limited to only backing out broken parts as much as possible to minimize surface area.
[Backout] - CL20029182
[FYI] josh.adams
Original CL Desc
-----------------------------------------------------------------
- Adding FConfigContext which is used to repalce LoadExternalIniFile, LoadLocalIniFile, etc, as well as have localized data for all configs read on a thread (like the other platform configs loaded in the editor)
- The Load*IniFile functions will create a Context, but eventually those APIs will go away and the Context will be the only way to load ini files
- Simplified some of the ini loading code, like removing the HierarchyCache (it wasn't helping editor load times, and added much complexity, and was not thread-safe, and it shouldn't actually be helpful because all the calls to Load*IniFile should eventually be replaced with either GConfig or FCOnfigCacheIni::ForPlatform(), which won't need to re-read in files
- Ini reading time actually went down due to the simplification, including Cache removal
- Left in old code for now behing a #define (USE_CONTEXT) in case something goes wrong
- Added in VERIFY_CONTEXT mode which I used to run original and Context modes and compare (including preflighting builds) (I also added a Compare function that we may want to keep around to use for future debugging)
- Added a separate set of config layers for plugins which speeds up plugin parsing, but also will fix the issue with BaseEngine.ini vs DefaultEngine.ini in Engine vs Project plugins (this shows how Contexts can bring useful information down into the guts - however a later change will enable it)
- Once this is all seen to be working, I will clean up the non-Context functions, and some globals vs static members, etc

PR #8567: Improve diagnostics for plugin version mismatch. (Contributed by zorbathut)
#preflight 628248becf7e4667a98c2c49
- I tweeked the log message slightly from the PR
-Worth noting that we don't need to localize this message even if it does feel a bit user facing as ::PromptToLoadIncompatiblePlugin will display a localized error message relating to the problem to the end user.

- Moved the IniCacheSet into the FConfigContext, and out of FConfigCacheIni. We could possibly get rid of it now entirely with the reduced number of paths we look for (and the fact that plugin scanning will be multithreaded soon)
- Removed the TRUEENGINE workaround now that Plugins are using a context to load the file, this makes the workaround unnecessary since plugins don't fake the EngineConfigDir

Config files are marked NoSave when plugin overrides them.
NoSave prevents issues with plugins leaving stale data around in config if turned off later.

- By setting "UE_DISABLE_PLUGIN_DISCOVERY=1" in its target.cs a stand-alone program can avoid the cost of iterating over all plugins but still load and enable specific plugins that it knows it needs.
- In the future we could make this data driven by allowing a program to supply something similar to the .upluginmanifest file.

This code path was intended primarily for Cooked / Packaged builds, where precaching all the INI files available in cooked files gave a significant reduction in startup times.
However, for editor builds, this actually causes significantly higher startup times (20s longer, or more).
