* This framework was a private framework before iOS 11.
This framework was a private framework before iOS 11, yet the headers claim
many API were introduced in iOS 10.
So take account of this difference by using the private framework location in
iOS 10.3 or earlier.
Testing these API from Xcode works fine when run on an iOS 10.3 device, and
I've confirmed the IOSurface framework is loaded from the private frameworks
path on older devices (and when built using Xcode 9 and linked with the public
framework path).
* Disable code to make IOSurface work on iOS 10.
Disable the code to make IOSurface work on iOS 10, since it may be rejected by
the App Store.
This also means adjusting the availability attributes, so that the
introspection tests pass (and to document that technically these API won't
work when used with Xamarin.iOS in iOS 10).
I've filed bug #[59201][1] to keep track of this, maybe we can re-enable this later.

`SkipDueToAttributeInProperty` which is used to check the availability attribute of properties
when the Availability info only exist on the property and not on the property Getter or Setter was wrong.
This lead to `setSpringLoaded` (which was introduced in iOS 11) to not be ignored by the test (making it fail).

Those tests needs to be run with the linker disabled since they use
reflection for most of their work.
The original dontlink (for linker tests) was becoming too large in
some configuration (e.g. tvOS release with bitcode) but this was
due to other BCL assemblies (not the introspection tests)
