Refactor Node class and TransformManagerproperty* class to optimize Object Size.

Refactor Node class and TransformManagerproperty* class to optimize Object Size.

Introduced TransformManagerData and keep a pointer instead of keeping
{TxManager, TxId} pair. hence reducing 8bytes per member.

Also templated  TransformManagerPropertyVector3 based on TransformManagerProperty to
avoid storing the Property type in the class object.

This patch reduced the Node size from 976 byte to 896 byte, saving 80 bytes per object.
