patch(build): Properly expose dependencies

The tooling API is now bundled into the JAR. Other dependencies are
exposed via feature variants. Consumers using figwheel should depend
on those specifically. Though in many cases, they might have direct
dependencies avoiding the need to use the feature variants.

We likely won't be able to publish this to Clojars, due to their
current lack of support for Gradle's module metadata. However, we
should be able to publish to Central while waiting for any solution
from Clojars themselves.
