Introduce dyn_star feature flag

Browse source 
The primary purpose of this commit is to introduce the
dyn_star flag so we can begin experimenting with implementation.

In order to have something to do in the feature gate test, we also add
parser support for `dyn* Trait` objects. These are currently treated
just like `dyn Trait` objects, but this will change in the future.

Note that for now `dyn* Trait` is experimental syntax to enable
implementing some of the machinery needed for async fn in dyn traits
without fully supporting the feature.
