Autocomplete keyframe animations when occluded on Windows 11 (#12820)

On certain builds of Windows, when Terminal is set as the default it
will accumulate an unbounded amount of queued animations while the
screen is off and it is servicing window management for console
applications.

This results in Terminal hanging when left overnight, as it has millions
of animations to process.

The new call into TerminalThemeHelpers will tell our compositor to
automatically complete animations that are scheduled while the screen is
off.

Fixes MSFT-38506980
