30955a1eb8 Take syntactic sugar into account when reporting errors 
Previously, a program like

```roc
word = "word"

if True then 1 else "\(word) is a word"
```

would report an error like

```
── TYPE MISMATCH ───────────────────────────────────────────────────────────────

This `if` has an `else` branch with a different type from its `then` branch:

3│  if True then 1 else "\(word) is a word"
                        ^^^^^^^^^^^^^^^^^^

This concat all produces:

    Str

but the `then` branch has the type:

    Num a

I need all branches in an `if` to have the same type!
```

but this is a little bit confusing, since the user shouldn't have to
know (or care) that string interpolations are equivalent to
concatenations under the current implementation.

Indeed we should make this fully transparent. We now word the error
message by taking into account the way calls are made. To support the
case shown above, we introduce the `CalledVia::Sugar` variant to
represent the fact that some calls may be the result of desugaring the
surface syntax.

This commit also demonstrates the usage of `CalledVia` to produce better
error messages where we use binary comparison operators like `<`. There
are more improvements we can make here for all `CalledVia` variants, but
this is a good starting point to demonstrate the usage of the new
procedure.

Closes #1714
