cpu: remove the declaration of function darwinSupportsAVX512

The implement of darwinSupportsAVX512 has been removed in CL 361255.
But the command "go install -buildmode=shared std" failed because the
declaration of it is remained in cpu/cpu_gc_x86.go. It should be removed.

Update golang/go#49233
For golang/go#49942
