display: Show the VRR range when possible

Context

This MR allows showing the full VRR range when possible instead of "up to". Showing the full range is more accurate than "up to" and may be easier to understand. This follows feedback from the community and discussions with @snwh.

Depends on:

• mutter!3576 (merged)
• !734 (merged) (included)

Description

From the commit message:

Show the full VRR (Variable Refresh Rate) range of a monitor in the
refresh rate expander row when a variable refresh rate mode is selected
and the minimum refresh rate of the monitor is known.
