This commit updates `wasmtime::FuncType` to exactly store an internal `WasmFuncType` from the cranelift crates. This allows us to remove a translation layer when we are given a `FuncType` and want to get an internal cranelift type out as a result. The other major change from this commit was changing the constructor and accessors of `FuncType` to be iterator-based instead of exposing implementation details.
