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

cpu: fix AVX512 support detection on Darwin
...
Summary: On darwin/amd64, it is not adequate to use OSXSAVE
bits to determine AVX512 availabilty. The reason is involved.
See github issue for details.
The fix consists of implementing Apple's recommended approach
using the process commpage cpu_capabilities bits to determine
availability of AVX512.
Fixes golang/go#43089
