Generalizes the build process for any LLVM version and any set of configuration options. To make it faster, the set of targets is reduced to only what we need for MrDocs. When we change the LLVM parameters, the first run will take slightly longer in CI and subsequent runs will reuse the cached binaries. This means we no longer need to host the binaries on mrdocs.com and update them manually, making the process of updating the LLVM version much simpler and cheaper since github will be hosting the binaries. It also allows us to explore other static ways to build LLVM in CI, which is required to create executables that are not associated with a specific ubuntu version. fix cppalliance#548
