That is, we should be able to reject allocation/instantiation for a component with more instances/tables/etc than a pre-configured limit, even when we actually have that much capacity in the pooling allocator.

This might exist in InstancePre, need to double check.

Either way, we should have typed errors for when you try to instantiate a component that lets you determine whether instantiation failed because there is not enough capacity for the component currently, or because the component is statically above the configured per-component limits on tables/memories/etc.

Right now this exists for modules as InstanceAllocator::validate and I think the solution here is "just" adding a component version of that. Note though that this is a compile-time check as opposed to a instantiation-time check, so you'd never run into a situation where a component could never be instantiated due to its limits.

That being said I think a descriptive error here is still good to have, since even if a component fits within the limits configured it can still fail to instantiate and it'd be good to understand why.
