[PATCH] D99621: [CMake][Compiler-rt] Make it possible to configure standalone compiler-rt without `LLVMConfig.cmake`.

@mstorsjo @phosek I've adapted this patch to changes in https://reviews.llvm.org/D99620 and I've hoisted the code out of `if (LLVM_CONFIG_PATH)`.  This required me to rewrite `compiler_rt_mock_llvm_cmake_config_set_target_triple` so that it no longer uses `llvm-config` because we can't assume it's available anymore. Instead we inspect the compiler being used and try to get a target triple from it.

A nice side benefit of the hoisting is that on Darwin I can actually now configure without needing `llvm-config` or `LLVMConfig.cmake` to be available.
