`getPlaceholderTemplateForComplication:withHandler:` was @required in
watchOS 2.x but is now deprecated and downgraded to @optional in
watchOS 3 (betas)
This is a breaking change but we have not released our final watchOS 2.x
bits yet so it make sense to backport this change (unless Apple reverts
it before 3.0 is released)
The types are not _publicly_ conforming to the protocols (i.e. the header
files don't mention them). However they do conform at runtime, which is
what the test check (so we must ignore them)
* Added CallKit Bindings
* Ensure CallKit.framework is linked
* Ensure CallKit passes introspection tests
* FIXME: https://trello.com/c/afWXDZ3A
Headers says CallKit is available on macOS 10.12
but uses AVAudioSession and it is iOS only

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)
