Switched to using SafeHandle for native code interrupt

Summary:
This PR fixes issue #295

- Created a new internal YGNodeHandle class extending SafeHandle.
- YogaNode now stores a reference to YGNodeHandle.
- Removed finalizer from YogaNode.
- Pulling in System.Runtime.Handles 4.3.0.
Closes https://github.com/facebook/yoga/pull/297
