In current GSI builds, AVB signing is not allowed.
We should allow signing GSI image, while building a vbmeta.img with
AVB_VBMETA_IMAGE_FLAGS_VERIFICATION_DISABLED (flag 2).
When need to disable AVB, use the vbmeta.img above together with the
GSI. When need enable AVB on GSI, include the GSI public key into the
device-specific vbmeta.img. Note that GSI is a chain partition so the
keys used to sign GSI and vbmeta.img are different.
Bug: 112293933
Test: build aosp_arm64-userdebug, checks flag 2 is set in vbmeta.img
and there is AVB HASHTREE in system.img
`avbtool info_image --image $OUT/system.img`
`avbtool info_image --image $OUT/vbmeta.img`
