What happened?

Inverting (__invert__) a DataArray or Dataset containing dask float data throws a ValueError with a message about the dimensions not matching the data. This should throw a TypeError with a message indicating an unsupported type for that operation.

What did you expect to happen?

I expected a TypeError with a relevant message about the type (shown below), not a ValueError with a misleading message.

```python import xarray as xr import dask.array as da

data = da.from_array([1.0]) x = xr.DataArray(data) ~x Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/USEr/anaconda3/envs/rstools/lib/python3.8/site-packages/xarray/core/_typed_ops.py", line 329, in invert return self._unary_op(operator.invert) File "/home/USER/anaconda3/envs/rstools/lib/python3.8/site-packages/xarray/core/dataarray.py", line 3078, in _unary_op da = self.array_wrap(f(self.variable.data, args, *kwargs)) TypeError: ufunc 'invert' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe'' ```

Minimal Complete Verifiable Example

```Python import xarray as xr import dask.array as da

data = da.from_array([1.0]) x = xr.DataArray(data) ~x ```

Relevant log output
