### Describe the bug, including details regarding any error messages,

When attempting to call `compute.count_distinct` on an array of UUIDs this
error is returned:
```
pyarrow.lib.ArrowNotImplementedError: Function 'count_distinct' has no
kernel matching input types (extension<arrow.uuid>)
```
Reproduce with:
```python
import uuid
import pyarrow as pa
import pyarrow.compute as pc
table = pa.Table.from_arrays(
[
[uuid.uuid4().bytes, uuid.uuid4().bytes],
],
schema=pa.schema(
[
pa.field("id", pa.uuid()),
],
),
)
unique = pc.count_distinct(table["id"])
```
