Added the UniffiAsyncCallHandler class. It follows the same basic pattern as UniffiSyncCallHandler, but for async calls. UniffiCallHandlerBase contains shared code between the two. Replaced `use_async_wrapper` with `call_style`, which returns 1 of three options rather than a boolean. This required a slight change to the async config for constructors. User now need to specify `Object.new` instead of `Object`. One upside is that it also allows configuring non-primary constructors. Added a test fixture for this. I used this fixture as an opportunity to sketch out how I think this would work with the application-services code and why this is an improvement over the current system for auto-generating async wrappers. Pass the buildconfig ENV when building the uniffi component libraries. We need this if we want to depend on crates like `moz_task`.
