### Describe the bug, including details regarding any error messages,
version, and platform.
Spinning off from #14814:
When testing round trips of empty arrays between Python and Go using the C
Data Interface, I found an issue with the binary and string data type arrays.
The data types: `pa.binary()`, `pa.large_binary()`, `pa.string()`,
`pa.large_string()` all throw an error when calling `validate(full=True)` after
the `_import_from_c` that contained a null value data buffer:
```
Traceback (most recent call last):
File
"/home/zeroshade/Projects/GitHub/arrow/go/arrow/cdata/test/test_export_to_cgo.py",
line 218, in test
b.validate(full=True)
File "pyarrow/array.pxi", line 1501, in pyarrow.lib.Array.validate
File "pyarrow/error.pxi", line 100, in pyarrow.lib.check_status
pyarrow.lib.ArrowInvalid: Value data buffer is null
```
Following up from #14805 clarifying that buffers can be null in a 0-length
array. My guess here is rather than the offsets buffer, the issue is the second
data buffer which would contain the actual binary/utf-8 data if the array had a
length >0. But that's just a theory, I haven't confirmed it.
