Support for multi-value wasm (#399)

Browse Source 
* deps: bump wasmparser to 0.39.2

This has a bug fix for multi-value Wasm validation that is required for getting
the spec tests passing.

https://github.com/yurydelendik/wasmparser.rs/pull/135

* Update cranelift to 0.46.1 to get multi-value Wasm support

The `cranelift_wasm` APIs had to change a little bit to maintain state necessary
when translating multi-value Wasm blocks. The `translate_module` function now
returns a `ModuleTranslationState` that is borrowed during each function's
translation.

* Enable multi-value proposal's spec tests

This enables all the Wasm multi-value proposal's spec tests other than the ones
that rely on functions having more return values than registers available on the
target. That is not supported by cranelift yet.

* wasmtime-interface-types: always use multi-value Wasm

And remove the return pointer hacks that work around the lack of multi-value.
