Emit non-defaultable unreachable local.sets#8858

Conversation
We recently started emitting local.sets of non-nullable locals after unreachable instructions that might be necessary for validation of subsequent local.gets. However, this did not properly handle tuple locals that contained non-nullable elements. Switch from using `isNonNullable` to using `isDefaultable` to determine which local.sets to emit.
