cpu: support reading arm64 CPU feature registers
...
This allows to detect ARM64 CPU features on non-Linux systems. On Linux,
this is used in case /proc/self/auxv cannot be read.

cpu: fix build for GOARCH=arm64 on GOOS!=linux
...
The current implementation for arm64 only supports linux (through HWCaps
read from /proc/self/auxv) and fails to build e.g. on darwin/arm64.
Fixes golang/go#30237

cpu: new package
...
This CL introduces a new cpu package for CPU/platform feature detection.
The cpu package is basically a copy of `internal/cpu` of the standard library.
Revision: bf86aec25972f3a100c3aa58a6abcbcc35bdea49
This CL does not export ARM64 and PPC64 feature detection since at the moment
ARM64/PPC64 requires standard library support.
Updates golang/go#24843
