Support building a boot.img for x86_64 GKI
e.g., the following config:
BUILD_GKI_ARTIFACTS=1
BUILD_GKI_BOOT_IMG_SIZE=67108864
will generate a boot.img under ${DIST_DIR} by packing
the kernel image ${DIST_DIR}/bzImage with an Android
boot v4 header.
Bug: 232906147
Test: BUILD_CONFIG=common/build.config.gki.x86_64 build/build.sh
Change-Id: I595187596da64c1863038ab6d0b67fa596b6111a
