Zheng, Gen b240450064 UEFI: change the acrn boot flow on uefi platform 
With current code, the acrn.efi is inserted between
cl bootloader.efi and bzImage.efi that destroyed the chain
relationship of cl bootloader and cl bzImage.efi.
And the following is current boot flow:
UEFI -> cl bootloader.efi -> acrn.efi -> bzImage.efi

The purpose of this patch is resume above chain relationship,
and make uefi vm return to efi stub context once launched,
then continue to call the UEFI API(LoadImage/StartImage) to launch
cl bootloader or other bootloaders. So the boot flow will
change to be as below:
UEFI -> acrn.efi -> cl bootloader.efi -> bzImage.efi

After applying this patch, the code related to loading
bzImage.efi and getting pe_entry is unnecessary due to
the bzImage.efi will not be launched by acrn.efi directly,
so it is removed.
