Clemens Backes a3776a6382 [wasm] Move ValueKind out of ValueType 
Backends do not care about the concrete type, they only need to know the
"kind" (e.g. "ref" or "i32").
In order to prepare Liftoff to use the value kind instead of the
value type for all stored data, this CL moves the kind out of the
ValueType and makes it a top-level enum.
