4bc9a024 - Replace lazy_tensors::StrJoin with c10::Join

Replace lazy_tensors::StrJoin with c10::Join Done with, ``` find lazy_tensor_core -name "*.cpp" | xargs sed -i -E "s/lazy_tensors::StrJoin\((.*), \"(. )\"\)/c10::Join\(\"\2\", \1\)/g" find lazy_tensor_core -name "*.cpp" | xargs sed -i -E "/str_join\.h/d" ``` Test by setting LTC_SAVE_TENSORS_FILE to dump IR and comparing before/after
