[BE] Make torch/csrc/jit/tensorexpr/ clang-tidy clean (#55628)
Summary:
Mostly auto-generated changes using
```
python3 tools/clang_tidy.py -c build -x torch/csrc/jit/tensorexpr/eval.cpp -s
```
With following common patterns manually fixed
- Use ` = default` instead of `{}`
- deleted methods should be public
- Use pass-by-value + std::move instead of pass-by-reference+copy
