Attachment: Bug 1690757 - Change compiler-rt cmake flags to better share with upcoming new platforms.

• Switch to use llvm-ar and llvm-ranlib
• Use CMAKE_*_COMPILER_TARGET for --target
• Use CMAKE_OSX_SYSROOT for -isysroot
• Limit the compiler wrapper to adding -mcpu=apple-a12 on arm64
• Remove -DLLVM_DEFAULT_TARGET_TRIPLE and add -DCOMPILER_RT_DEFAULT_TARGET_ONLY=ON
• Group all the flags that are OSX-only
