In preparation for eventual support for wasm interface types this commit moves around a few panics internally inside of conversions between the `wasmtime` crate and the underlying jit support crates. This should have any immediately-visible user changes, but the goal is that this'll help support interface types which means `wasmtime` will have types that are not supported by wasmtime itself and we'll be able to more gracefully support that with error messages instead of accidental panics.
