Rationale for this change
FromScalar creates metadata slices with a non-zero length and then appends to them. Each decoded metadata entry therefore gets an extra empty key and value.
What changes are included in this PR?
Build the slices with zero length and the required capacity, then add a metadata round-trip regression test.
Are these changes tested?
go test ./arrow/scalarAre there any user-facing changes?
No API changes. This corrects the reported behavior while preserving the existing ownership and compatibility contracts.
