Improve suggestions for malformed deprecated attribute
When the deprecated attribute is supplied a single string as an argument, suggest using the NameValueStr syntax.
```
error[E0565]: malformed `deprecated` attribute input
--> $DIR/deprecation-sanity.rs:24:5
|
LL | #[deprecated("test")]
| ^^^^^^^^^^^^^------^^
| |
| didn't expect a literal here
|
help: try using `=` instead
|
LL - #[deprecated("test")]
LL + #[deprecated = "test"]
|
```
If the string looked like a version (e.g. `"1.2.3"` or `"TBD"`), suggest using the since field instead.
```

help: try specifying a deprecated since version
