recipes: Rework llvm/clang/compiler-rt/libcxx/lldb recipes

This is an overhaul of clang/llvm project related recipes

* switch to using a flat mono repo for all clang/llvm projects
* Add llvm-project-source recipe which will prepare source tree in
  work-shared for all recipes much like kernel and gcc
* build lld as part of clang recipes, its much easier and saves build
  time and hopefully nativesdk version will be built now for free
* switch to official git repos at git://github.com/llvm-project
* Adjust all recipes to use shared sources
