[mlir][sparse] Implement missing BufferizableOpInterface methods for NewOp (#178423) ## Summary Fixes crash when running `--eliminate-empty-tensors` on MLIR modules containing `sparse_tensor.new` with a tensor input. ## Problem The `sparse_tensor.new` operation was missing the `bufferizesToMemoryRead`, `bufferizesToMemoryWrite`, and `getAliasingValues` methods in its `BufferizableOpInterface` implementation. This caused an `UNREACHABLE` crash with message "bufferizesToMemoryRead not implemented". ## Solution Implemented the missing methods in `NewOpInterface`: - `bufferizesToMemoryRead`: returns `true` (reads from source tensor) - `bufferizesToMemoryWrite`: returns `false` (doesn't write to source) - `getAliasingValues`: returns empty (result is new allocation, not an alias) Also added a test case for `sparse_tensor.new` with tensor input.
