Implement the graphic menus

As we plan to show localized rescue party dialogs under recovery mode
with pre-generated images, it becomes necessary to show the menu headers
and items with images.

This cl converts the menu class to a interface and derived TextMenu &
GraphicMenu classes. And the GraphicMenu uses GRSurfaces* as the menu header
and a list of GRSurfaces* as menu items.

Moreover, factor out the Draw* functions in the ScreenUI into a separate
DrawInterface. Therefore, the Menu class can access these draw functions and
use them to implement the DrawHeaders & DrawItems neatly.

Bug: 74397117
Test: unittests pass, boot into recovery and check menu
