This commit moves the internals of the `ResourceAny` type related to destructors into the auxiliary data within a `Store`. This avoids the need to carry around pointers with `ResourceAny` and additionally makes it easier to work with. As part of this commit this also updates the behavior of `ResourceAny::try_from_resource` to no longer need an `InstancePre` and type information. This was required originally to get `ResourceAny::resource_drop` working to drop the host resource. In retrospect I'm not sure if this was the best goal to achieve because `Resource<T>` already has no destructor support and one of the more common use cases for the conversion is to simply turn around and give it back to a component where a component already has enough destructor information. In the end this should make both `ResourceAny` and `Resource<T>` pretty close to "just an index" which is easier to reason about when working with resources than carrying additional pointers.

Looks great, thanks.
Should ResourceIndex be removed altogether and not be returned anymore by LinkerInstance::resource?
It appears that this PR closes #7714

Good points! And sorry again for not realizing this is probably the best way to go sooner, I realize this is a bit of a runaround with the API :( |
