host: define new interface for checking condition

With the introduction of the PLDM protocol as a mechanism to communicate
with the host firmware, a more specific mechanism is needed for BMC
software to check if the host is running. Utilizing the generic
Execute() method is confusing, especially considering that all of the
Command types may not be supported by all protocols.

The plan is to deprecate the Control.Host, Execute() with the HeartBeat
command type, in place of this new interface and property. Both IPMI
and PLDM will implement this method and BMC software can query mapper
for implementers on their specific systems.
