[vm] Add Native->VM transitions when dereferencing API handles.
For example setting return value unwraps handles and stores raw pointer values to the stack which might race with GC in another thread. This CL adds assertions in helper methods from Api class which unwrap API handles and fixes all places that were revealed by those assertions. Caveat: we still permit to check whether handle contains Smi or not without entering VM state - because GC does not change this property.
