Support clearing columns via `DataTable.clear()`
Looks like this feature must have gotten lost in the shuffle, since the docstring mentions it but the function doesn't support it: https://github.com/Textualize/textual/blob/3aaa4d3ec1cfd1be86c781a34da09e6bc99e8eff/src/textual/widgets/_data_table.py#L315-L328

Happy to do a PR for this. Is it as simple as running `self.columns.clear()` if the `columns` argument is `True`?
