Lock display refresh rate when primary range is a single rate.

When DMS enforces a fixed refresh rate to hide user-visible flickering,
we must respect that refresh rate to avoid unnecessary switches during
scenarios such as idle and touch boost.

We must still respect app votes when they explicitly provide a frame
rate.
