Arraydebug

- Allows `array_like.__array__()` to throw exceptions.
- Now, `array_like_info(obj)` degrades to vanilla `repr(obj)` if `obj.__array__()` throws exception. Before, it did nothing, but let caller to handle the exception.
- rename `arraydebug.recover_repr()` to `arraydebug.disable()`.
- rename `arraydebug.inject_repr()` to `arraydebug.enable()`.
- `enable()` also refresh `arraydebug.repr_fn_table` now.
