(This is a merge of http://go/wvgerrit/13813) Removes the OS Version property which was only ever implemented on Android to appease Netflix and never actually used by them. Adds, instead, a Widevine library version property. Also adds implementations of this function for both Android and CE Devices. For Android, the version number is starting at 3.0.0-android, to reflect that this is the third major revision of the Widevine CDM in Android. For CE Devices, the version number is not changing from its current value (2.2.0) but is gaining a "-ce" on the end in order to differentiate it from the Android version number.
