ArmPkg/PlatformBootManagerLib: fall back to the UiApp on boot failure
As a last resort, drop into the UiApp application when no active boot
options could be started. Doing so will connect all devices, and so
it will allow the user to enter the Boot Manager submenu and pick a
network or removable disk option. With the right UiApp library added
in, the UiApp also gives access to the UEFI Shell.
