[tensor] add shape consistency feature to support auto spec transform

[YuliangLiu0306]

This PR construct a ShapeConsistencyManager class to manage the shape consistency behaviour, it mainly does three things:

1. Give a pair of source spec and target spec, it will give you a valid transform path with greedy algorithm.
2. It will cached the transform path of all searched pairs, so most of time when you apply the shape consistency transform, the transform has already cached in manager, it won't cost additional time to search the path again.
3. It will give an apply function to implement the sharding spec to the tensor.

Note: The ShapeConsistencyManager class is just partially completed.
