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

This is used when dealing with PDB files that are over 4GB.
Use -PdbPageSize=<value> on the UBT command line, or add this to BuildConfiguration.xml:
<WindowsPlatform>
<PDBPageSize>32768</PDBPageSize>
</WindowsPlatform>
Expected values are 4096 (default), 8192, 16384, 32768
Note to select an installed preview build of VS, you need to specify
<WindowsPlatform>
<CompilerVersion>Preview</CompilerVersion>
</WindowsPlatform>

Our stack size defaults to 4.7M on Windows, so allowing functions to use more stack space in favor of going through the heap.

UnrealBuild -> Unreal for EngineDirectory, RootDirectory, IsEngineInstalled, UnrealBuildToolPath
Remove CommandUtils EngineDirectory, RootDirectory, IsEngineInstalled - use equvalents from UnrealBuildBase.Unreal

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.

RootDirectory, EngineDirectory, UnrealBuildToolPath are now found in BuildUtilities' UnrealBuild namesapce.
The way these are computed has changed. Previously, it was assumed that the application is UnrealBuildTool, and paths were constructed relative to that assembly.
Now, the assumption is that the process is located under a "Engine/Build/DotNET" sub-path and paths are constructed relative to that.

Default is still VS2019, running `GenerateProjectFiles.bat -2022` will create a solution and projects that pass -2022 to UnrealBuild tool when compiling from Visual Studio to force it to use the 2022 toolchain.
Please note, as the defaults are unchanged building from UnrealGameSync will still compile with VS2019 so I would disable that build if testing VS2022.
None of this is necessary to use VS2022, it can open VS2019 solutions and will use the Vs2019 toolchain to build.

Also fixed the flag format, for consistency, now that they support the '/' variant for it, which early builds didn't.

Note that up until VS 16.9, according to the MSVC blog, ASan requires explcit helper libraries to be added to the linker line, which requires knowledge of what type of CRT we're compiling with on the link side.
