console: add a clear_screen() primitive
Several places in e.g. MokManager and our console library use
ST->ConOut->ClearScreen directly, without checking for the existence of
a console output device.
This patch adds function to our console library to do that correctly,
instead of using the bug-prone ad hoc implementation everywhere.
