Add a lint for Function parameter trailing comma

To give an example of what the linter should reject/fix:

```hcl
merge(
  local.a,
  local.b,
  local.c
)
```

should become

```hcl
merge(
  local.a,
  local.b,
  local.c,
)
```

I did not check the linting code, but syntactically my suggestion is very similar to the existing lint. So perhaps this is a very easy to accomplish improvement.
