firmware: host: futility: Add CBFS metadata hash supportstabilize-15183.14.B
This patch adds support for signing and verification of coreboot images
supporting VBOOT_CBFS_INTEGRATION. Images with config option
CONFIG_VBOOT_CBFS_INTEGRATION=y will be signed with CBFS metadata hash
in signature. vb2api_get_metadata_hash() should be used to extract hash
value from VBLOCK and then should be used to verify CBFS metadata.
To support full verification, CBFS file data verification should also be
enabled and correctly handled.
BUG=b:197114807
TEST=build with CB:66909 and boot on volteer/voxel with
CONFIG_VBOOT_CBFS_INTEGRATION=y
BRANCH=none
