Thomas Braun 25a59b59f2 Github Actions: Add ClangCL on Windows
MS Visual Studio 2019 has builtin support for other compiler toolsets [1].

This commit adds support for compiling using LLVM/Clang 10 using Visual
Studio.

ClangCL pretends to be MSVC so the usual MSVC flags apply, see also [2].
For detecting if ClangCL is used, newer cmake verisons (>= 3.15) have
builtin support using CMAKE_CXX_COMPILER_FRONTEND_VARIANT [3], for older
ones a workaround is available using CMAKE_CXX_SIMULATE_ID [4].
