  Create a driver to update StageMode Interactions based on Gesture Input

Reviewed by Richard Robinson, Elliott Williams, and Wenson Hsieh.

This PR adds the StageModeInteractionDriver, which is a helper class object used in the ModelProcessModelPlayerProxy
to control how the model responds to the stagemode transform updates, based on the applied stagemode attribute. When
stagemode is set to 'none' we ignore all transforms passed to the player proxy. When stagemode is set to 'orbit' we
use the translation from the transform to rotate the model. To separate stagemode updates from Javascript updates,
we introduce an Interaction Container that wraps around the model entity, on which the stagemode updates will be applied.

The driver will be implemented in https://bugs.webkit.org/show_bug.cgi?id=287601.
