Resolves #8613

Since check_name have already got a parameter to show name help, I reuse the logic and sync the behavior between cargo init and cargo new. The divergence seems to be intentionally made in #7959:

...Only print the --name suggestion for cargo init.

Feel free to discuss.

I feel like suggesting --name is a little unusual here. The common case doesn't seem likely to be "I want to create an unusual directory name but name the project something different"; that's not a pattern we should actively encourage. The common case is likely to be "Oh, I should use a different directory name". Steering people towards --name doesn't seem like the right answer.

How does something like "if you need the directory name to not match the project name consider the --name flag" sound?

Just rephrase as "If you need a crate name to not match the directory name, consider using --name flag." So the whole message would be something like

[ERROR] invalid character `¼` in crate name: `a¼`, characters must be Unicode XID characters (numbers, `-`, `_`, or most letters)
If you need a crate name to not match the directory name, consider using --name flag.

I did not choose the suggestion approach mentioned in this comment because in real world the situation is more complex and may lead to suggest another invalid name.
