Add Ruffle type definitions

Browse source 
These can be replaced later when Ruffle API v1 releases with proper TypeScript definitions and such: https://github.com/ruffle-rs/ruffle/pull/17939
I am planning to do so myself when that happens.
For now, Dinnerbone has graciously provided us with type definitions of the current API.

* For users of `ruffle-core` as a npm module, you are encouraged to call {@link installRuffle} once during page load to

* For this reason, you are required to call `window.RufflePlayer.latest()` (for example) to grab the latest {@link SourceAPI},
* from which you can create a {@link PlayerElement} via {@link SourceAPI.createPlayer}.
