This patch sets the MemoryOverwriteRequestControl (MORCtrl for short)
EFI variable before jumping to hypervisor.
Setting variable MemoryOverwriteRequestControlLock (MORCtrlLock for
short) can also be enabled by manually adding -DMORCTRL_LOCK_ENABLED to
CFLAGS.
Setting MORCtrl indicates to the platform firmware that memory be
cleared upon system reset. Setting MORCtrlLock for the first time will
render both MORCtrl and MORCtrlLock to read-only, until next reset.

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.
