RFR: 8342647: [macosx] Clean up the NSInvocation based call to NSProcessInfo.operatingSystemVersion [v2]

[Jaikiran Pai]

> Can I please get a review of this change which does a tiny cleanup in the macosx specific code in `java_props_macosx.c`?
> 
> As noted in https://bugs.openjdk.org/browse/JDK-8342647 the `setOSNameAndVersion` function used to dynamically call `NSProcessInfo.operatingSystemVersion` because that property wasn't (statically) available until macosx 10.10 version. Since that version this property has been available even in the latest macosx versions https://developer.apple.com/documentation/foundation/nsprocessinfo/1410906-operatingsystemversion, so it's now possible to statically reference it in the code.
> 
> The change in this PR replaces the use of `NSInvocation` with the static reference to this property. No new tests have been added. Existing tier1, tier2 and tier3 tests with this change have all passed.
