8617ff654a cpu: add frequency support for apple silicon m1/m2 cpus 
This PR adds support for reading the frequency of Apple Silicon
M1/M2 CPUs. We do so by reading the values out of the IOKit
framework, as a few other projects have now demonstrated to be
possible. This requires the use of CGO. The library provides a
convenience IsAppleSilicon() guard to detect whether the values
can be read.

Currently gopsutil does not support the big.LITTLE CPU architectures
(i think?) - in fact the P and E cores have different max frequencies.
For now, just read the P core frequency. The E core data is readily
available if we want to read it in the future.

Closes #1000

Small example program

```go
package main

import (
        "fmt"

        "github.com/shoenig/go-m1cpu"

        "github.com/shirou/gopsutil/v3/cpu"
)

func main() {
        fmt.Println("is Apple Silicon:", m1cpu.IsAppleSilicon())
        fmt.Println("model name", m1cpu.ModelName())
        fmt.Println("pCore GHz", m1cpu.PCoreGHz())
        fmt.Println("eCore GHz", m1cpu.ECoreGHz())
        fmt.Println("pCore Hz", m1cpu.PCoreHz())
        fmt.Println("eCore Hz", m1cpu.ECoreHz())

        fmt.Println("----- gopsutil ----")

        infos, err := cpu.Info()
        if err != nil {
                panic(err)
        }

        for _, info := range infos {
                fmt.Println("info.Mhz", info.Mhz)
        }
}
```

```shell
go run main.go
is Apple Silicon: true
model name Apple M2 Pro
pCore GHz 3.504
eCore GHz 2.424
pCore Hz 3504000000
eCore Hz 2424000000
----- gopsutil ----
info.Mhz 3.504e+09

ee12f66e4d cpu, v3/cpu: use sysconf package instead of exec'ing getconf 
Currently, ClocksPerSec is determined by exec'ing getconf in func init,
i.e. on startup of every program importing the package. getconf might
not be present on some systems or is not executable by the current user.
To avoid this hard to control dependency, use the
github.com/tklauser/go-sysconf package which implements sysconf(3)
entirely in Go without cgo. The package is supported on all platforms
currently supported by the cpu and v3/cpu package of gopsutil.

123a6c9b0d Addressing frequency unit discrepancies 
* for Darwin, it is a minor tweak for readability: the value
  returned is in Hz, so using a variable named 'hz' makes more
  sense than 'mhz'
* for Linux, the unit is in kHz so we need to divide the value
  from `cpuinfo_max_freq` by 10^3 to get MHz (see
  cpu-freq/user-guide.txt of the kernel documentation)
