Ben Dean-Kawamura f25b21537e Bug 1918512 - Support for async Rust calls, r=nika,markh
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`.
