ObjC: Add a Xcode project for tvOS.

The CocoaPod (and source) have always support tvOS, but adding the project
makes it easier to run the tests and debug if there ever were an issue.

(not adding a watchOS project at the moment because Apple doesn't provide
 XCTest, so all it could do is build the library. We still support that,
 just can't "test" it.)
