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.

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.

1. not need 'clean' when building ACRN-HV/DM each time
2. correct efi-stub wrong dependency

Add the below flags, they are needed in -O2:
-fno-delete-null-pointer-checks:
* tells the compiler NOT to assume that null pointer deference does
not exist.
* Without this flag, below case cannot be detected:
a pointer might point to nullsometime during run-time and if there
is no validation for that pointer, it will cause the program to crash.
Since we don’t receive an error message saying that a pointer is
pointing to null, we will have a hard time trying to find the problem.
-fwrapv:
* tells the compiler that signed overflow always wraps.
* Without this flag, x + 10 > x will always be true for signed x.
With the flag, x + 10 > x is not always be true, as the overflow is
defined for x, and it could wrap.

To be back compatible, the default acrn.efi should be built when
BOARD param is nuc6cayh, because apl-nuc was overridden to nuc6cayh
in acrn-hypervisor/Makefile;

1. if SCENARIO=$(SCENARIO) is specified in make param, then override
the default CONFIG_$(SCENARIO) value in existed .config. This means
we don't need to modify the default SCENARIO config in Kconfig file
to build the hypervisor;
2. Some board name shortcuts like apl-nuc/kbl-nuc-i7 need to be converted
to official board name to make sure overrides working;
3. Previously make sbl-hypervisor did not load the defconfig so the
defconfig for boards are lost, this patch fix this issue;
4. remove SCENARIO param when make hypervisor, because SCENARIO could
be got from SCENARIO_NAME which parsed from .config;

We are trying to add both industry and sdc images to CL build. To
maintain the build interface unchanged (no change from CL side), we
extend the build command to generate the different target images.
To identity different images, we use rule:
$(HV_FILE).$(BOARD).$(FIRMWARE).$(SCENARIO)
as target image file name.
