Providing the line length, max-complexity, etc in --statistics

@JonathanPlasse

Similar to #3748 but for providing the value for `line-length`, `max-complexity`, `max-args`… when running `ruff --select=ALL --statistics .`

When linting a new repo, I might need to set all seven of the following numbers.
```toml
[tool.ruff]
line-length = 100 # Recommended: 88

[tool.ruff.mccabe]
max-complexity = 15 # Recommended: 10

[tool.ruff.pylint]
max-args = 8 # Recommended: 5
max-branches = 17 # Recommended: 12
max-returns = 12 # Recommended: 6
max-statements = 52 # Recommended: 50
```
It takes a bit of trial and error to find the length of longest line or the most complex function. It would save a lot of time and aggravation if `--statistics` did not just show a random `E501` error but instead showed me the error message from the longest line. I could the copy that `line-length` value and paste it into `pyproject.toml`

Run `ruff --select=ALL --statistics .` on a representative repository and inspect how the current statistics output reports E501 and complexity-related violations. Done means the output exposes the observed values needed to configure `line-length`, `max-complexity`, `max-args`, `max-branches`, `max-returns`, and `max-statements`.
