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

Per-project rules assembly csprojen.
Previously: all .build.cs and .target.cs were being grouped into a single project, which resulted in duplicate symbols when trying to build the project.
Now: multiple assemblies csprojs are generated, one for each Engine & Game project. Also, includes preprocessor defines.

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.

Move NativeProjects partially into BuildUtilities - class split to avoid pulling in a larger chain of dependencies.
#jira none
[CL 16608480 by jonathan adamczewski in ue5-main branch]
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.

* Filter out numerous source files that match */Source/ThirdParty/* that should have already been filtered, this does not include Module.Build.cs or .tps files, or if bGatherThirdPartySource is enabled
* Filter out source files that match */third_party/* by default
* Add option bIncludeDotNetPrograms to remove all ..NET projects, doing so saved me around 400MB. Note if you disable the .NET projects UnrealBuildTool won't build before compiling (but GenerateProjectFiles.bat will still build it)
Attempted changes that did not reduce memory usage by a significant amount:
* Filtering out project configurations
* Filtering out Engine/Shaders or Engine/Content/Editor/Templates
* Increasing the shared include size, even making it large enough to contain every include path didn't really make a difference. Also it can't really be increased anyway because that entire property is added to the process environment when starting a build and there's a max environment size of around 32k
Other Fixes:
* Fix vs2019 ToolVersionString 15.0 -> 16.0
* Add VCProjectVersion to Project globals
* Update UniqueIdentifier GUIDs in projects to be stable by hashing the directory path and using that hash as the GUID
* Don't write ProjectConfiguration if filtered out (Didn't affect memory usage)
* Add optional configuration filter for Debug, DebugGame, & Development
