Add ScreenRecoveryUI::ShowMenu().
From caller's PoV, RecoveryUI::{Start,Select,End}Menu should always be
used together, i.e. to show a menu and get user's selection. This CL
provides ShowMenu() as one-stop service (which is based on
get_menu_selection() from recovery.cpp).
Also move RecoveryUI::{Start,Select,End}Menu into ScreenRecoveryUI, with
a dropped access level from public to protected.
Due to the dependency on recovery / librecovery refactoring, will add
testcases in follow-up CLs.
Test: Build and boot into recovery image. Check the menus (main menu,
'View recovery logs', 'Wipe data/factory reset').
