Match minimum supported versions from the WIKI [0] by raising them to: - GCC 9.3.1 - CLANG 8.0 - MVCS 2019 (16.9.16 / 1928) Details: - Add CMake checks that ensure supported compiler versions early on. - Previously GCC per-processor version checks served to exclude `__clang__`, in some cases this has been replaced by explicitly excluding `__clang__`. This was needed as CLANG treated some of these flags differently to GCC, causing the build to fail. - Remove USE_APPLE_OMP_FIX GCC-4.2 OpenMP workaround. - Remove linking error workaround for old MSVC versions.
