[BugFix][Fusion] Patch compile backend to make fusion available (#5308)

Currently, the vllm pr: https://github.com/vllm-project/vllm/pull/24252
is causing operator fusion to fail, which can be mitigated by patching
the backend. Once the problem is completely resolved, I will submit a
new pull request to remove the patch.

+#    Why:
+#       vllm removed the compile graph for general shape, which caused operator fusion to fail.
+#       This issue affects the performance of model inference on Ascend.
+#    How：
+#       recover the compiled graph for dynamic_shape in PiecewiseBackend.
