Enable PIN auto-submit feature on the lock and login screen.

The PIN auto-submit feature changes how PINs are entered in Chrome OS.
Instead of showing the same textfield that is used for password input, this
feature shows a special UI that clearly shows to the user how many
digits are necessary for their PIN. As a consequence, the user's PIN length
will be stored outside the user encrypted data. Only supports PINs that are
between 6 and 12 digits long.

If this policy is set to false, users will not have the option of enabling
the feature on the Settings page.

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
