The header is now added to the working set rather than the generated source file.

Verified relative pathing works fine for msvc clang builds
Use .d files for dependencies when compiling with windows clang, instead of piping through cl-filter.exe
Use relative pathing for generated unity files

Add a StringComparison argument to CreateIntermediateTextFile() and require callers to make a decision about the case-sensitivity used when considering whether to re-write a file.
(This is intentionally explicit and verbose at the call-site - we should implement a better solution. This change makes it clear that there is work to be done to be able to simplify the interface and achieve reliable behavior.)
As a first pass, C++ files (headers, cpp files, pch files) will have a case-sensitive comparison (C++ code is, mostly, case sensitive), Linux script files have a case-sensitive comparison (case-sensitive filesystem), and all other files are compared disregarding case - to match pre-existing behavior, and with the desire to not borrow more surprises than necessary.

- Exclude source files from unity if their first include is in the working set.
- Compile header files in the working set in their own dedicated source file if there is not an existing source file that includes it first.

Any build targets have a DefaultBuildSettings property. For engine targets, this defaults to BuildSettingsVersion.Latest. For project targets, this defaults to BuildSettingsVersion.Release_4_23. For new projects, this will default to the engine version they are created from.
If a target is not using the latest default build settings, they will receive a message describing the settings that have changed, like this:
[Upgrade]
[Upgrade] Using UE 4.23 compatible build settings. The latest version of UE4 sets the following values by default, which may require code changes:
[Upgrade] bLegacyPublicIncludePaths = false => Omits subfolders from public include paths to reduce compiler command line length.
[Upgrade] PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs => Set in build.cs files to enables IWYU-style PCH model. See https://docs.unrealengine.com/en-US/Programming/BuildTools/UnrealBuildTool/IWYU/index.html.
[Upgrade] Suppress this message by setting 'DefaultBuildSettings = BuildSettingsVersion.Release_4_24;' in UnrealPak.Target.cs, and explicitly overriding desired settings.
[Upgrade]
Intent is to reduce friction for users initially upgrading to new engine versions, while notifying them of more optimal build settings being available, and letting them choose when (or if) to use them.

Live++ reads object files at startup for game modules, and assigns unique ids to each compiland (used to disambiguate static variables). When compiling the patch, these compilands are modified to reference a unique id for the unity blob, causing the variables to be reconstructed.
Solution is to generate a JSON file to each output directory containing object files containing the mapping, and to use that to assign compiland ids at startup.

- This allows for Confidential platforms to exist outside of the engine, and insert themselves in as needed
- Directory structure is, where .... mirrors the directory structure for Engine and projects
- /Platforms/XXX/....
- Moving to more data driven approach for ShaderPlatforms and PlatformInfo, where they can be read from DataDrivenPlatformInfo.ini files that live in the platform config folders
- Removed platform mentions from UBT, by way of changing some enums to partial classes with static members (see UnrealTargetPlatform)
- Various other UBT/UAT modifications to allow for looking in other locations for files
- THIS IS NOT A COMPLETE AND FINAL SOLUTION. WE WILL CONTINUE WORK IN DEV-BUILD BEFORE ITS READY FOR PRIMETIME

These variables (and their dynamic initializers) were being treated as new, rather than being linked back to their original instances. UBT now outputs a mapping of object files to their original unity object file during a live coding compile, which allows Live++ to disambiguate between new and reconstructed instances.
