b0d78208 - [libc] Move __LLVM_LIBC__ define to __llvm-libc-common.h (#126877)

[libc] Move __LLVM_LIBC__ define to __llvm-libc-common.h (#126877) Relying on features.h is problematic since codebases are free to have such a header on their search path, which breaks compilation. libc should instead provide a more standard way of getting __LLVM_LIBC__. Since __llvm-libc-common.h is included from all libc headers, defining __LLVM_LIBC__ there ensures that this define is available whenever any of the standard header is included.
