[I] [C++] Create registry for Devices to map DeviceType to MemoryManager in C Device Data import [arrow]
jorisvandenbossche opened a new issue, #40698:
URL: https://github.com/apache/arrow/issues/40698
### Describe the enhancement requested
Follow-up on https://github.com/apache/arrow/pull/39980#discussion_r1483235845
Right now, the user of `ImportDeviceArray` or `ImportDeviceRecordBatch` needs to provide a `DeviceMemoryMapper` mapping the device type and id to a MemoryManager. We provide a default implementation of that mapper that just knows about the default CPU memory manager (and there is another implementation in `arrow::cuda`, but you need to explicitly pass that to the import function)
To make this easier, the suggestion was to create a registry such that default device mappers can be added separately.
