vboot: Rename legacy UIs

According to crbug.com/1033815, rename files and entry point functions
for two legacy UIs. Ideally, these UIs will be deprecated after the
detachable UI revamp (b:146399181) is done.

common:
- rename vboot_ui_common.{c,h} to vboot_ui_legacy_common.{c,h}

LEGACY_CLAMSHELL_UI:
- rename vboot_ui.c to vboot_ui_legacy_clamshell.c
- rename vboot_ui_wilco.c to vboot_ui_legacy_wilco.c
- rename VbBootRecovery() to VbBootRecoveryLegacyClamshell()
- rename VbBootDiagnostic() to VbBootDiagnosticLegacyClamshell()
- rename VbBootDeveloper() to VbBootDeveloperLegacyClamshell()

LEGACY_MENU_UI:
- rename vboot_ui_menu.c to vboot_ui_legacy_menu.c
- rename vboot_ui_menu_private.h to vboot_ui_legacy_menu_private.h
- rename VbBootRecoveryMenu() to VbBootRecoveryLegacyMenu()
- rename VbBootDeveloperMenu() to VbBootDeveloperLegacyMenu()
