git_commit commit cffc1ac3491c891ef4f80bcbfa685710e477eeac

[libc++] Avoid including <features.h> on arbitrary platforms (#125587)

This partially reverts commit 5f2389d4. That commit started checking
whether <features.h> was a valid include unconditionally, however codebases
are free to have such a header on their search path, which breaks compilation.
LLVM libc now provides a more standard way of getting configuration macros
like __LLVM_LIBC__.

After this patch, we only include <features.h> when we're on Linux or
when we're compiling for GPUs.
