Original change's description:
> [skottie] Add onTextProperty support into PropertyObserver.
>
> This effectively allows observing/modifying properties at the text document level. By default
> Bodymovin exports even static TextDocuments as a single keyframe, so the unit-tests have been
> updated to store the property handles for verification.
>
