Adding BOARD_BUILD_GKI_BOOT_IMAGE_WITHOUT_RAMDISK 

GKI targets, e.g., `gki_arm64` or `gki_x86_64` have only
boot-*.img files without a ramdisk. It has no other images,
e.g., init_boot.img, system.img, etc.

The current build system assumes that the ramdisk is either
in a boot.img or in a init_boot.img, which is not true for
those GKI targets. Adding a new flag to support building
boot-*.img without a ramdisk while not building an init_boot.img.

Bug: 220834917
Test: build and `unpack_bootimg`
