[JIT] Cleanup some places where we log graphs in executors. (#44588) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/44588 1) SOURCE_DUMP crashes when invoked on a backward graph since `prim::GradOf` nodes can't be printed as sources (they don't have schema). 2) Dumping graph each time we execute an optimized plan produces lots of output in tests where we run the graph multiple times (e.g. benchmarks). Outputting that on the least level of verbosity seems like an overkill. 3) Duplicated log statement is removed.
