Fix memory leak in dynamic ECS example (#11461)
# Objective

- Fix a memory leak in the dynamic ECS example mentioned in #11459

## Solution

- Rather than allocate the memory manually instead store a collection of
`Vec` that will be dropped after it is used.

---

I must have misinterpreted `OwningPtr`s semantics when initially writing
this example. I believe we should be able to provide better APIs here
for inserting dynamic components that don't require the user to wrangle
so much unsafety. We have no other examples using `insert_by_ids` and
our only tests show it being used for 1 or 2 values with nested calls to
`OwningPtr::make` despite the function taking an iterator. Rust's type
system is quite restrictive here but we could at least let
`OwningPtr::new` take non u8 `NonNull`.

I also agree with #11459 that we should generally be trying to simplify
and clarify this example.
