Nvfuser - Type Promotion Fix
Fix Type Promotion failures in [Issue 76046](https://github.com/pytorch/pytorch/issues/76046)
1. Updated nvfuser type promotion rule for codegen kernel;
2. Updated casting for output of nvfuser kernel to respect profiling/TorchScript scalar type;
3. Updated type_inference.cpp to only update device/scalar_type when profiling information is missing.
Additional Type Promotion Fixes:
