vboot: Introduce menu UI

According to crbug.com/1033815, add files for MENU_UI:
- 2ui.{c,h} for entry point functions called by kernel selection.
- vb2_ui_tests.c for tests (normal boot included).

There are three entry points: vb2_developer_menu(),
vb2_broken_recovery_menu(), and vb2_manual_recovery_menu().

Only infinite loop for this CL, others will be added in separate CLs.
