feat: suggestions for ambiguous dotted identifiers (#11555)
This PR scans the environment for viable replacements for a dotted
identifier (like `.zero`) and suggests concrete alternatives as
replacements.

## Example

```
#example .zero
```

Error message:
```
Invalid dotted identifier notation: The expected type of `.cons` could not be determined
```

Additional hint added by this PR:
```
Hint: Using one of these would be unambiguous:
  [apply] `BitVec.cons`
  [apply] `List.cons`
  [apply] `List.Lex.cons`
  [apply] `List.Pairwise.cons`
  [apply] `List.Perm.cons`
  [apply] `List.Sublist.cons`
  [apply] `List.Lex.below.cons`
  [apply] `List.Pairwise.below.cons`
  [apply] `List.Perm.below.cons`
  [apply] `List.Sublist.below.cons`
  [apply] `Lean.Grind.AC.Seq.cons`
```

## Additional changes

This PR also brings several related error message descriptions and code
actions more in line with each other, changing several "Suggested
replacement: " code actions to the more common "Change to " wording, and
sorts suggestions obtained from searching the context by the default
sort for Names (which prefers names with fewer segments).
