[PR] fix(arrow/array): propagate embedded pointer nullability [arrow-go]

["fallintoplace (via GitHub)" <gi...@apache.org>]

fallintoplace opened a new pull request, #1038:
URL: https://github.com/apache/arrow-go/pull/1038

   ## What changed
   
   Carry nullability through anonymous embedded pointer paths while collecting reflected struct fields.
   
   ## Why
   
   A promoted non-pointer field beneath an embedded pointer can be absent when that pointer is nil. The array builder already emits a null in that case, but schema inference marked the field non-nullable because it only inspected the leaf field type.
   
   This change makes the inferred schema agree with the values produced by the builder, including for multi-level embedded pointer paths.
   
   ## Validation
   
   `go test ./arrow/array/arreflect`
