This is for GKI 1.0 devices to pass VtsHalKeymasterV4_0TargetTest.
For GKI 2.0 devices, they will use device-specific
BOOT_SECURITY_PATCH to sign a prebuilt GKI boot.img to
override this value.
See https://r.android.com//1711437 for details.

There are GKI arm64 and x86_64 now. The patch restructures the
GKI common settings to a new common BoardConfig file
"BoardConfigGkiCommon.mk".
It includes the ramdisk and boot image settings for GKI.
The patch also removes obsolete TARGET_PRELINK_MODULE.
