meta-ampere: host-check: verify the host state

When phosphor-state-manager handles the power action to turn on the
host, phosphor-state-manager does not use the software interfaces to
verify the host state. It set the host state to running after all of
required services of the power action target are done. The power on
watchdog is used to verify the host state and handle the failure in
the host state changing. But Mt.Jade platforms do not handle power on
watchdog. This causes the CurrentHostState dbus property is Running
before the host is ready.

In Mt.Jade platform, the SCP drives S0_FW_BOOT_OK to high when the
host is already on. This GPIO can be used to identify the host state.
One service should be added to the required list. This service checks
the host state in power on and triggers obmc-host-quiesce@%i.target
when the host is failed to boot. ampere-host-check package adds
ampere-host-on-host-check@.service for that purpose.

Tested:
    1. Boot up BMC with the host is off/on. Check CurrentHostState.
    2. Call Ipmitool power off/on. Check the CurrentHostState.
    3. Call Ipmitool chassis power off/on. Check the CurrentHostState.
    4. Call Ipmitool power cycle. Check the CurrentHostState.
    5. Call Ipmitool chassis power cycle. Check the CurrentHostState.
    6. Power off the host. Set power policty to Always-on. AC power.
    The host should be on. And CurrentHostState should be Running.
    7. Power on the host. Set power policty to Always-off. AC power.
    The host should be off. And CurrentHostState should be Off.
