Refactor YogaNode.Inputs freeze API

Browse Source 
Summary:
`InternalNode` will eventually not have a pointer to its parent. This diff removes one of the usages of the `InternalNode#getParent()` API. `InternalNode` will also not host the `YogaNode` eventually; so this diff also removes one of the usages of the `InternalNode#getYogaNode()` api.

Now the `Inputs#freeze` api will pass the parent's `YogaNode` and the `YogaNode` of the node (this) being measured.

Changelog: [Internal] Passes The YogaNode and parent YogaNode in the Inputs.freeze API
