Current Toolchain.defs set the compile flags directly, it's OK for target specified gcc toolchain. But some LLVM based toolchains (Rust/Zig etc) use single toolchain to handle all supported paltform. In this patch, arch level Toolchain.defs export standard LLVM style arch flags, and let <Lang>.defs to map them into internal style, This will simplify the intergration of non-c language.
