ArmPlatformPkg/Bds: Added support for booting legacy kernel from BDS

Browse Source 
When PcdBdsLinuxSupport is enabled, users can create boot
entries for the legacy EFI Linux loader.

The ARM BDS detects if the image is a EFI image if not
then it assumes it is a legacy Linux kernel (a kernel
without EFI Stub).
If the Boot Manager did not manage to load the binary
(it could happen when the binary is on the network or
not present on the media yet).
