This consists of essentially two changes:

- Set up more things needed when running tests; include the llvm-lit directory, set LLVM_DEFAULT_TARGET_TRIPLE, make sure that LLVM_MAIN_SRC_DIR is set
- Move certain settings from llvm-project/runtimes to llvm-project/llvm/runtimes. Only set LLVM_RUNTIMES_BUILD if invoked from llvm/runtimes, otherwise the build works as fairly normal standalone build. Don't try to forcibly add -nostdinc++ -nostdlib++ in llvm-project/runtimes. If llvm-project/runtimes is used for building runtimes standalone, one can be building that with e.g. GCC, and we can't assume clang-specific options without a check.

Plus the change to libcxx ci to add the new build configuration of course.
