Enforce property split in GSI

Pure GSI build targets has no vendor partition, such as
aosp_$arch_ab and gsi_$arch. The system properties defined by
PRODUCT_PROPERTY_OVERRIDES will be in /system/build.prop.

The patch defined a fake BOARD_VENDORIMAGE_FILE_SYSTEM_TYPE to
let these system properties flow to vendor and won't pollute the
system.img.

The bug also move some properties to /product/build.prop.
