host-state-manager: Add multi-host support

Add support management multiple host state with multi process.
Each process obtain a d-bus object for corresponding host.

TESTED : Built the openbmc image for Facebook Bletchley hardware.
Verified Host State buses/objects created successfully

root@bletchley:~# busctl tree xyz.openbmc_project.State.Host1
└─/xyz
  └─/xyz/openbmc_project

Built with host id 0 :
expose both Host and Host0 name to keep backwards compatibility.
