This reverts commit 5eb5978043c8e7036e15572e. The change was problematic: *Advanced users may prefer managing schemes manually and adding only a few that they need, instead of one for every library/executable Blender builds. *If CMake creates schema files, it overwrites the changes a developer made every time CMake is run. If Xcode creates scheme files, it keeps settings/ environment variables intact. If someone runs CMake very frequently, pass `-DCMAKE_XCODE_GENERATE_SCHEME=ON` to `cmake` while configuring.
