This resolves a UBT issue where building from Visual Studio/Rider while the editor is running wouldn't automatically change to HotReload mode.

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.

Make ShouldDoHotloadFromIDE() more robust against the possiblity that the PID of a long-gone Editor instance has been recycled as a system process.
