add setFocus to MD2D view, use on non-embed page load

[#42517011]

Now when using the Next/Previous buttons to sequence through
Interactives after the Interactive loads the keyboard
focus is set to the MD2D view.

This allows a user/tester to start or stop the model using
the keyboard controls.

The MD2D view option: enableKeyboardHandlers must be true
for the keyboard controls to work. This is set true by default
only when the play_reset_step playback control is used.
enable keyboard handlers for all Interactives

[#42517011]

This now allows a tester to start any model in the non-embeddable
Interactive page by using the keyboard commands after the
Interactive is loaded.

Many models can be quickly tested by clicking the "Next" button
and then pressing either "space" or "Return" to start the model.
