[C++][Compute] Function 'utf8_trim' has no kernel matching input types (dictionary<values=string, indices=int64, ordered=0>)

[chaokunyang]

Describe the bug, including details regarding any error messages, version, and platform.

Arrow compute function utf8_trim doesn't support dictionary array:

File ~/anaconda3/envs/py3.8/lib/python3.8/site-packages/pyarrow/_compute.pyx:367, in pyarrow._compute.Function.call()

File ~/anaconda3/envs/py3.8/lib/python3.8/site-packages/pyarrow/error.pxi:144, in pyarrow.lib.pyarrow_internal_check_status()

File ~/anaconda3/envs/py3.8/lib/python3.8/site-packages/pyarrow/error.pxi:121, in pyarrow.lib.check_status()

ArrowNotImplementedError: Function 'utf8_trim' has no kernel matching input types (dictionary<values=string, indices=int64, ordered=0>)

Reproduction script:

da = pa.DictionaryArray.from_arrays(pa.array([1,2,1,2,1,2,0,0]), pa.array(["abc", "b", "a"]))
pc.utf8_trim(da, characters="bc")

Decode DictionaryArray into StringArray will work.
