too. See new test.

This commit also fixes some macros, and make sure the elaborator still
works, but it does not support multiple sources yet.

578b3b822f fix: do not use nullKind for group combinator 
We use `nullKind` for the `group` parser combinator.
When pattern matching `nullKind` nodes, we check their arities.
So, error recovery often fails for parsers that use the `group`
combinator.
For example, we have the parser
```
def whereDecls := leading_parser "where " >> many1Indent (group (letRecDecl >> optional ";"))
```
If there is syntax error at `letRecDecl`, the node corresponding to
```
group (letRecDecl >> optional ";")
```
will contain only one child, and the pattern matching at
```
def expandWhereDecls (whereDecls : Syntax) (body : Syntax) : MacroM Syntax :=
  match whereDecls with
  | `(whereDecls|where $[$decls:letRecDecl $[;]?]*) => `(let rec $decls:letRecDecl,*; $body)
  | _ => Macro.throwUnsupported
```
fails, and we can't elaborate the partial syntax tree for
`letRecDecl`, and auto-completion will not work there.

We address this issue by using a new kind for the `group` combinator.
The idea is to pattern match `group` as we pattern match `node`s with
proper syntax node kinds. This change is consistent with the way we
use `group` where it mainly a convenience for saving us the trouble of
defining a new parser definition that is used only once.

be841a7cad chore: throwError! => throwError, throwErrorAt! => throwErrorAt 
@Kha I marked the corresponding methods as `protected`.
I currently can't stand `throw_error`, and I am optimistic about
server highlighting feature you are working on :)

68143ca8ba chore: trace[...]! ==> trace[...] 
@Kha I think this one is a good change, there is no real reason for
using the `!` suffix here.

d6f778bec4 refactor: arbitrary without explicit arguments 
@Kha I was tired of writing `arbitrary _` :)
There 0 places in the stdlib where the type needs to be provided.
If in the future we need to specify the type we can use
`arbitrary (α := <type>)`
