feat: heterogeneous Append experiment
...
@Kha This one required a bunch of manual fixes. The main issue is that
before we added the string interpolation feature, we created
`MessageData`s using `++` and coercions. For example, given
`(e : Expr)`, we would write
```
let msg : MessageData := "type: " ++ e
```
and rely on the coercions `String -> MessageData` and
`Expr -> MessageData`, and the instance `Append MessageData`.
However, heterogeneous operators "block" the expected type propagation downwards.
This kind of code is obsolete now since we can write a more compact
version using string interpolation
```
let msg := m!"type: {e}"
```

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>)`

fix: #eval was not capturing dbgTrace! output in pure code
...
In the following example, the output produced by `dbgTrace!` was not
being captured. It could break the lean server. At least, it broke the lean4-mode.
```lean
def f (x : Nat) : Nat :=
dbgTrace! ">>> " ++ toString x;
x + 1
eval f 10
```
