### Describe the enhancement requested [dictionary_encode](https://arrow.apache.org/docs/cpp/compute.html#associative-transforms) takes an Array as input and converts it into a DictArray. However, it does not let you set the encoding. Users would then need to afterwards use the [Transpose](https://arrow.apache.org/docs/cpp/api/array.html#_CPPv4NK5arrow15DictionaryArray9TransposeERKNSt10shared_ptrI8DataTypeEERKNSt10shared_ptrI5ArrayEEPK7int32_tP10MemoryPool) API to set the encoding they'd like - a step which does involve a copy. Having both of these API is great, but is there anything blocking us from expanding `dictionary_encode` so that it accepts a transpose map? ### Component(s) C++ -- This is an automated message from the Apache Git Service.
