Reviewed by Jer Noble.

Declared an Objective-C interface for WKSLinearMediaPlayer and a protocol for
WKSLinearMediaPlayerDelegate. The interface is implemented in Swift, where it conforms to the
Playable protocol. The properties exposed to Objective-C are bound to Publishers via key-value
observing, and Playable functions are exposed to Objective-C via the delegate. Since
@_objcImplementation classes can only contain stored properties representable in Objective-C,
Swift-only types are stored indirectly via SwiftOnlyData.
