ArmPkg/PlatformBootManagerLib: Add path to boot UEFI Shell over UiApp
The UEFI Shell is a non-active boot option, at the opposite of UiApp. If no valid boot option is found, UiApp is selected. UiApp requires a human interaction. When installing a new EDKII image in CIs or when scripting is required, this is problematic. If no valid boot option is discovered, add a path to directly go to the UEFI Shell where the startup.nsh script is automatically executed. The UEFI Shell is launched after connecting possible devices, but before the reset that is meant to automatically make them visible. The new PcdUefiShellDefaultBootEnable must be set to TRUE to enable this behaviour. The Pcd is set to false by default.
