Alex Crichton 3ed6fae7b3 Add trampoline compilation support for lowered imports (#4206)
* Add trampoline compilation support for lowered imports

This commit adds support to the component model implementation for
compiling trampolines suitable for calling host imports. Currently this
is purely just the compilation side of things, modifying the
wasmtime-cranelift crate and additionally filling out a new
`VMComponentOffsets` type (similar to `VMOffsets`). The actual creation
of a `VMComponentContext` is still not performed and will be a
subsequent PR.

Internally though some tests are actually possible with this where we at
least assert that compilation of a component and creation of everything
in-memory doesn't panic or trip any assertions, so some tests are added
here for that as well.

* Fix some test errors

//! Support for the component model in Wasmtime.
//!
//! This module contains all of the internal type definitions used by Wasmtime
//! to process the component model. Despite everything being `pub` here this is
//! not the public interface of Wasmtime to the component model. Instead this is
//! the internal support to mirror the core wasm support that Wasmtime already
//! implements.
//!
//! Some main items contained within here are:
//!
//! * Type hierarchy information for the component model
//! * Translation of a component into Wasmtime's representation
//! * Type information about a component used at runtime
//!
//! This module also contains a lot of Serialize/Deserialize types which are
//! encoded in the final compiled image for a component.
//!
//! Note that this entire module is gated behind the `component-model` Cargo
//! feature.
//!
//! ## Warning: In-progress
//!
//! As-of the time of this writing this module is incomplete and under
//! development. It will be added to incrementally over time as more features
//! are implemented. Current design decisions are also susceptible to change at
//! any time. Some comments may reflect historical rather than current state as
//! well (sorry).
