[CUPS] Implement the "Printers" section in chrome://settings.

The CUPS printer setup UI is currently implemented under MD Settings.

Because we are planning to launch CUPS with M56 and CrOS MD Settings
will launch in a following milestone, we implement the "Printers" section
in current chrome://settings to link to the CUPS printer MD settings UI
from the existing chrome://settings.

Note: This change is temporary and will be reverted later in M57.
