Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Using arrow::compute::kernels::filter::filter and arrow::compute::kernels::filter::filter_record_batch on arrays (or record batches respectively) containing UnionArray produces a panic such as

panicked at 'not yet implemented: Take and filter operations still not supported for this datatype', arrow/src/array/transform/mod.rs:520:17

Describe the solution you'd like
It should work

Context
See example in #1379 from @helgikrs for MapArray support
