DataSync: Added the "BMCData" interface (#158)

- Introduced a new interface, "BMCData," to facilitate syncing BMC data
  between redundant BMC systems, as outlined in the following design
  document, https://gerrit.openbmc.org/c/openbmc/docs/+/71039.

- This interface can be implemented by application to enable data
  synchronization services in redundant BMC setups.

- The interface is started with an object path to allow application
  to host and manage data sync services.
