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.

- Previously, any changes made to AutoSDKs had to be submitted along with a bump in the version string returned by GetRequiredScriptVersionString(). Since this string is in UBT, the string has to be bumped in every branch where we need the AutoSDK changes to get applied.
- Now, the script version string is stored in Version.txt, meaning there's only one place the version needs to be bumped to force all UBT instances in all branches to reapply an SDK.
- Made GetRequiredScriptVersionString() private and removed platform implementations.

* Added C++20 flags for all the recognized compilers.
