* Split `wasm_to_host_trampoline` into pieces In the upcoming component model supoprt for imports my plan is to reuse some of these pieces but not the entirety of the current `wasm_to_host_trampoline`. In an effort to make that diff smaller this commit splits up the function preemptively into pieces to get reused later. * Delete unused `for_each_libcall` macros Came across this when working in the object support for cranelift. * Refactor some object creation details This commit refactors some of the internals around creating an object file in the wasmtime-cranelift integration. The old `ObjectBuilder` is now named `ModuleTextBuilder` and is only used to create the text section rather than other sections too. This helps maintain the invariant that the unwind information section is placed directly after the text section without having an odd API for doing this. Additionally the unwind information creation is moved externally from the `ModuleTextBuilder` to a standalone structure. This separate structure is currently in use in the component model work I'm doing although I may change that to using the `ModuleTextBuilder` instead. In any case it seemed nice to encapsulate all of the unwinding information into one standalone structure. Finally, the insertion of native debug information has been refactored to happen in a new `append_dwarf` method to keep all the dwarf-related stuff together in one place as much as possible. * Fix a doctest * Fix a typo
