Add an OOM-handling `TryCow` type and `TryToOwned` trait (#12669)

These are like `std::borrow::Cow` and `std::borrow::ToOwned` but return
`OutOfMemory` errors on allocation failure.

Add fallible `try_collect` to collections (#12505)

* Add fallible `try_collect` to collections

This adds a new `TryCollect` extension trait to `wasmtime-core` which
enables `iter.try_collect()` to fallibly collect into a `Vec<T>` or
`Box<[T]>` while handling OOM. This is intended to serve as a
replacement for the `new_boxed_slice_*` helpers in appropriate
situations since it more closely matches what Wasmtime likely already
does today where we throw `.collect()` on iterators.

* Extend oom tests a bit more

* Use a TryExtend trait
