Wire up global styles

[dmjio]

Per yesterday's latest PAPI drop, consider including global style objects loaded before the application begins (similar to what miso does here).

We should abstract out src/Miso/Internal.hs:renderStyles into our rendering layer abstraction (context.ts) and use the below functions as the implementation for native. This plays a role with adding @keyframes in #3

  function __CreateStyleObject(styleObject: Object): StyleObjectRef;
  function __SetStyleObject(elementRef: ElementRef, styleObjects: Array<Object>): void;
  function __UpdateStyleObject(styleObjectRef: StyleObjectRef, styleObject: Object): void;
  function __ElementAnimate(node: ElementRef, animateArgs: Object): void;

miso currently supports inline styles via the __Inline* style family of PAPI functions
