refactor(langchain): remove model_rebuild (#32080)

Browse Source 
Since #29963 BaseCache and Callbacks are imported in BaseLanguageModel
so there's no need to import them and rebuild the models.
Note: fix is available since `langchain-core==0.3.39` and the current
langchain dependency on core is `>=0.3.66` so the fix will always be
there.
