[wasm] Disallow using stack-backed handles in runtime-wasm.cc

We currently don't have a way to visit parameter stack slots being
passed from Wasm to the runtime during GC, so while we usually access
them as if they were handles, they're not actually GC-safe in this
case. Until we find a way to fix this differently, force manual creation
of safe handles.
