Add proto dumpstate mode

Add a "PROTO" dumpstate mode to request a protobuf dump from
IDumpstateDevice HAL, primarily used by incidentd to get
device-specific state as a proto for automated issue reporting and
debugging.
Since the format of these states can vary across vendors and devices,
the proto schema will not be defined in AOSP.
