Generate verity config.
A new minor version 6 kVerityMinorPayloadVersion is added, client
having a minor version >= 6 means it support writing verity hash
tree and fec given verity config from payload.
When generating payload in Android, if the source minor version is
>= 6, then we try to find the AVB footer for each partition image
and parse the AVB hashtree descriptor, if found then write verity
config to the payload, the verification of verity config will be
added in a follow up CL.
AVB is an Android specific format, so we will skip this for Chrome
OS for now, if later we decided to enable verity feature in Chrome
OS, we can implement the parsing logic for Chrome OS verity metadata
format in payload_generation_config_chromeos.cc
