chore: polish `ArrowDeviceArray` (#8023) ## Changes - Generate Arrow C Device ABI bindings from a vendored Arrow reference header - Fixed VarBin/Utf8 Arrow export layout by reporting the correct `n_buffers = 3` - Fixed Bool export to ensure buffers are resident on the CUDA device - Fixed struct child `ArrowArray` lifetime/release handling - Replaced unsupported-export panics with recoverable errors - Added schema normalization so exported schemas match the physical Arrow Device layout (`Utf8View`/`BinaryView` → `Utf8`/`Binary`) ## Notes This PR is scoped to Arrow Device array export. The intent is to build cuDF support in a follow up on top of this. --------- Signed-off-by: Alexander Droste <alexander.droste@protonmail.com>
