Switch the i386-efi and x86_64-efi builds to the generic EFI loader, which enters the Linux kernel via the EFI stub and provides the initrd via the LoadFile2 protocol. This unifies x86 with other EFI architectures, and removes the dependency on the setup header and struct bootparams.
Do some preparatory cleanup first, so we no longer need to rely on the MS to SysV calling convention translation code. Changes since v2: - rebase onto latest master, which has the Loongarch changes - retain Itanium support for now - simplify the fallback logic - attempt to load the image as usual, and fallback on failure or if the image does not implement LoadFile2 Changes since v1: - drop Itanium support, which is a maintenance burden as it shares the EFI code with other architectures, but does not have a EFI stub in Linux, and there is no way to test whether our changes break the boot for it or not; - enable generic EFI for i386 as well - wire up the existing x86 code as a fallback for kernels that lack EFI stub or LoadFile2 support. This removes the need for additional changes to support v5.8 or older kernels.
