Setup api module

[fractalwrench]

Goal

Creates an embrace-android-api module. This will contain some but not all of our public facing API, as we want our core module to have access to some but not all symbols in our public API, but obviously want to maintain visibility for end-users.

This required a bit of an alteration to how Dokka is configured but was otherwise a reasonably straightforward change.
