44817b8488 feat: autoParam takes the Name of an auxiliary declaration of type Syntax 
@Kha The `Name` (tactic name) approach used in Lean3 is not suitable
for Lean4. The issue is that we define tactics using macros, and in
most cases, the user doesn't even know the node id.

ae84270226 feat: include result of sequence of macro expansions 
@Kha I added this feature to help debugging macros.
I was using `set_option trace.Elab true` as a workaround, but it is
too verbose.
For example, in the following buggy code

```
new_frontend

macro "foo" x:term : term => `(x + 1)
macro "bla" x:term : term => `(foo $x)
```

We get the error message
```
<input>:6:11: error: unknown identifier 'x.15'
with resulting expansion
   x  +  1
while expanding
   foo 1
while expanding
  bla 1
```

Perhaps we should preserve the macroscopes at "with resulting
expansion". Anyway, I think it is better than the previous error.

```
<input>:6:11: error: unknown identifier 'x.15'
while expanding
   foo 1
while expanding
  bla 1
```

e817257922 feat: elaborate declare_syntax_cat 
TODO: `registerParserCategory` uses `registerAttribute` which relies
on the environment having a declaration of type `AttributeImpl`.
This is bad since forces users to import `Init.Lean`.

@Kha The key problem is that we cannot serialize `AttributeImpl`.
I will try to address this issue tomorrow. I am considering different
workarounds.
