Introduce QAbstractChannelMapping

This will act as the base class for the various specific use cases:

* QChannelMapping for mapping to ordinary QNode properties
* QSkeletonMapping for mapping to indexed joints in a skeleton
* QCallbackMapping for calling a callback in response to an animation

The last two of these are yet to be added. The final one is
currently part of QChannelMapping but will be separated from it.

All 3 types can map to the same type ChannelMapping backend node.
