misc: efi-stub: Barebone efi-stub for secure boot ACRN EFI application based on the legacy efi-stub code provides booting method of HV on UEFI-BIOS without using the GRUB Bootloader. It is supposed to be used for secure booting on certain platform. By means of that users can boot HV, Service VM kernel, pre-launched VM kernel and its ACPI table binary packed in the Slim Bootloader container boot image file format. ACRN EFI application has additional dependencies to compile which are not listed in the existing ACRN GSG doc. Since this is an optional feature but not all users need, it does not get compiled by default to avoid causing any confusion for existing users. README for how to use the feature will come later in a separated commit. This patch adds barebone implementation of this efi-stub. The following files are reused from a previous version of efi-stub without changes: efilinux.h, pe.c, stdlib.h Other files contains stubbed functions, whose implementation will come in coming patches.

misc: efi-stub: Add barebone container as an implementation of HV_LOADER Previous patches introduces an abstract struct HV_LOADER to do two things: load boot image and load boot modules. This patch provides an implementation barebone of container. The implementation of critical functions container_load_boot_image and container_load_modules will come in coming patches.
