This is a preparation commit for removing the setup_console(1) calls from MokManager and shim so that we don't force the EFI console to switch to text-mode. This commit replaces all direct calls to Print / PrintAt with calls to the new helpers (no functional changes) so that we can delay calling setup_console(1) till the first Print call in a follow-up patch.
