`MacDevice`: changed usage of `kIOMasterPortDefault` to fix Catalyst compilation on Xcode 14 (#1676)
`MacDevice`: changed usage of `kIOMasterPortDefault` to fix Catalyst compilation on Xcode 14 (#1676)

From the docs:
```
@abstract The default mach port used to initiate communication with IOKit.
@discussion When specifying a main port to IOKit functions, the NULL argument indicates "use the default". This is a synonym for NULL, if you'd rather use a named constant.
extern
const mach_port_t kIOMainPortDefault
```

`kIOMasterPortDefault` is deprecated, and `kIOMainPortDefault` isn't available on Catalyst in Xcode 14. This fixes compilation by simply using `NULL` (0).

Fixes [CSDK-106].
