Move GKI common settings to BoardConfigGkiCommon.mk

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.
