ArmPkg/Application/LinuxLoader: Create a Linux Loader EFI application

Browse Source 
There are two variants of the Linux Loader EFI application:
- the ATAG version 'LinuxAtagLoader.inf': expect to start an ATAG 'zImage'
in the same directory as the EFI application
- the FDT version 'LinuxFdtLoader.inf': load the FDT blob 'platform.dtb'
and the FDT 'zImage' from the same directory as the EFI application.

When these applications are started without any argument, a menu appears
to the user to create/update a boot entry.
