Audit usages of toOwnedSlice (#32001)

Browse Source 
Followup to #30769

I grepped for `try .*toOwnedSlice` and checked all of them by hand.

Fixes a bunch of memory leaks removes usages or `errdefer` and `vars` in some places. I also switched array_list.Managed to ArrayList where it was convenient.
