This pull request adds more suggestion to unexpected cfg names and values diagnostics:

  • it first adds a links to the rustc unstable book or the Cargo reference, depending if rustc is invoked by Cargo
  • it secondly adds a suggestion on how to expect the cfg name or value:
    excluding well known names and values
    • for Cargo: it suggest using a feature or cargo:rust-check-cfg in build script
    • for rustc: it suggest using --check-cfg (with the correct invocation)

Those diagnostics improvements are directed towards enabling users to fix the issue if the previous suggestions weren't good enough.

r=me on everything except is_cfg_a_well_know_name (#118213 (comment)), that part can be submitted as a separate PR an I'll maybe look how it's possible to avoid hard-coding it later, but not right now.

Fix invalid check-cfg Cargo feature diagnostic help

rust-lang#118213 added specialized diagnostic for Cargo `feature` cfg. However when providing an empty `#[cfg(feature)]` condition the suggestion would suggest adding `feature` as a feature in `Cargo.toml` (wtf!).

This PR removes the invalid logic, which even brings a nice improvement.

```diff
   --> $DIR/cargo-feature.rs:18:7
    |
 LL | #[cfg(feature)]
-   |       ^^^^^^^
+   |       ^^^^^^^- help: specify a config value: `= "bitcode"`
    |
    = note: expected values for `feature` are: `bitcode`
-   = help: consider defining `feature` as feature in `Cargo.toml`
```

The first commit add a test showing the bug and the second commit fixes the bug.
