SecurityPkg OpalPasswordDxe: gray out menu instead of suppress it.

For current implementation, if the device is pyrite type, driver
will suppress the "keep user data" option. Base on the feedback
from user, they prefer to keep the menu but gray out it. Now base
on this feedback to update the driver.
