Which issue does this PR close?
Rationale for this change
Because
Arc<dyn Array>(ArrayRef) implementsArray, it's easy to create redundantArc<Arc<dyn Array>>. The extra indirection is pure overhead (both cognitive and runtime) with no benefit.What changes are included in this PR?
Remove the redundant wrapping.
Are these changes tested?
Compilation suffices -- failing to wrap a concrete array type in Arc would cause compilation failures.
Are there any user-facing changes?
No.
