[FEATURE]: accelerate auto-parallel intra-op solver solving time

[YuliangLiu0306]

Describe the feature

The solving time for auto-parallel intra-op solver is unacceptable for LLMs as the number of layers increasing.

We could do following steps to reduce the solving time for LLMs:

1. find largest repeated blocks.
2. Use an alias set to force all repeated blocks sharing a same distributed training strategies.
