Revert "Revert "Revert "Replace dynamic summary text for SettingPref"""

This reverts commit c1e9f8787f.

Reason for revert: There is an issue when dropdown menu text has a '%' sign in it.
Despite testing it on my own devices, the bug did not show up immediately.

Instead of continuing down this path for OC, we'll just revert
this patch, and then as an ugly, band-aid solution, check the
summary text for the "%s" substring, and hide it when found.
In O-DR onward, we'll look for a more permanent solution.
