Huang Qi 536739d2da tools: Export LLVM style arch info for non-c language
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.
