Description
The binary_join kernel currently supports:
list(string), string
list(large_string), large_string
it should support:
fixed_size_list(string), string
fixed_size_list(large_string), large_string
**Reporter**: [Weston Pace](https://issues.apache.org/jira/browse/ARROW-13945) / @westonpace

Research direction
Start at the C++ binary_join kernel and compare its current list(string) and list(large_string) handling with the related fixed-size-list compute-functions issue. Done means binary_join supports fixed_size_list(string) with string and fixed_size_list(large_string) with large_string, with coverage for both combinations.
