Works around this bug in unix-compat: https://github.com/jacobstanley/unix-compat/issues/56 getFileStatus and other FilePath using functions in unix-compat do not do UNC conversion on Windows. Made Utility.RawFilePath use convertToWindowsNativeNamespace to do the necessary conversion on windows to support long filenames. Audited all imports of System.PosixCompat.Files to make sure that no functions that operate on FilePath were imported from it. Instead, use the equvilants from Utility.RawFilePath. In particular the re-export of that module in Common had to be removed, which led to lots of other changes throughout the code. The changes to Build.Configure, Build.DesktopFile, and Build.TestConfig make Utility.Directory not be needed to build setup. And so let it use Utility.RawFilePath, which depends on unix, which cannot be in setup-depends. Sponsored-by: Dartmouth College's Datalad project
