Seth Hoenig 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 ----

test: use `T.Setenv` to set env vars in tests 
This commit replaces `os.Setenv` with `t.Setenv` in tests. The
environment variable is automatically restored to its original value
when the test and all its subtests complete.

feat: Setting the model name for arm based CPUs 
- Added arm model and model name as map.
- The modelName is set again according to the model value when the model name is empty.
- Based on lscpu source code.. https://github.com/util-linux/util-linux/blob/master/sys-utils/lscpu-arm.c

Merge pull request #1244 from omar-polo/master 
fix cpu_openbsd.go once and for all
Omar Polo 73f9c8dfd5 avoid cgo for cpu_openbsd 
Even thought OpenBSD often breaks the ABI compatibility and doesn't make
*any* promise of "stability", this project aims to be "pure go" so avoid
doing inter-op at the cost of artificially reducing the number of
supported architectures down to amd64 and i386.

To add support for another architecture (e.g. arm), add another file
cpu_openbsd_${arch}.go like done for 386 and amd64.  The fields are
declared as `long' in C, so pick the appropriate size when declaring the
struct.
Omar Polo 3c3c017f23 avoid copying kernCPUStats
Omar Polo 57d5711d44 refactor TimesWithContext 
don't make assumptions on which CPUs are online and wich aren't based
on hw.smt and hw.ncpuonline.  Rather, use KERN_CPUSTATS to get the CPU
statistics, which includes a flag field that can tell us if that CPU
is online or not.
Omar Polo 16cc7d7d73 improve sysctl parsing: use native byte order 
We can't use unix.Sysctl* for some sysctls, so we're on our own with
converting data from C arrays.

Don't assume that the byte order is little endian but do the right
thing.  Moreover, there's a little distinction in the sizes reported
by KERN_CPTIME (long[cpustates]) and KERN_CPTIME2
(u_int64_t[cpustates]) so account for that too.
