```
macos: reimplement OS version detection

The macOS version is now obtained by parsing `SystemVersion.plist`.

Test cases added for plist files that date back to '2005 Panther and up
to the recent '2020 Big Sur 11.1 release of macOS.

Thus we are now able to reliably identify 10.3...11.1 and higher.

- drop use of kern.osproductversion sysctl
- drop use of kern.osversion sysctl (fallback)
- drop kern.osversion tests
- add `lib.std.zig.system.detect()`
- add minimalistic parser for `SystemVersion.plist`
- add test cases for { 10.3, 10.3.9, 10.15.6, 11.0, 11.1 }

closes #7569

```
