Now CMake and compilation flags are functionally equivalent with the current master branch, not taking into account the deprecated flags. Also various small improvements to building.
...
Deprecated flags:
* BUILD_DEBUG. This was redundant since CMake also has such flag. The build type can now be switched by passing -DCMAKE_BUILD_TYPE=<Release|Debug|RelWithDebugInfo|...> to cmake. See CMake documentation on CMAKE_BUILD_TYPE on all av
* BUILD_UTILS. The utility library is now always built along the core library. We can reintroduce this flag if needed when the library grows larger. Currently MPI functions depend on Utils and without the flag we don't have to worr
* BUILD_RT_VISUALIZATION. RT visualization has been dormant for a while and I'm not even sure if it works any more. Eventually the RT library should be generalized and moved to Utils at some point. Disabled the build flag for the t

Simplified/rewrote the root CMakeLists.txt s.t. compilation bugs are easier to pinpoint. WIP, not all functionality is yet enabled (primarily compilation options like MPI_ENABLED and others)

Reordered src/core to have better division to host and device code (this is more likely to work when compiling with mpicxx). Disabled separate compilation of CUDA kernels as this complicates compilation and is a source of many cmake/cuda bugs. As a downside, GPU code takes longer to compile.

src/utils is now a real library. Includable with the astaroth_utils.h header and linkable with libastaroth_utils.a. The purpose of Astaroth Utils is to function as a generic utility library in contrast to Astaroth Standalone which is essentially hardcoded only for MHD.

Simplified the include directory. Everything is now in only two headers: astaroth.h and astaroth_utils.h. Removed old and unused stuff. user.h is unused in standalone but might be used with Pencil Code, so left that intact.
