schemas: Add Decorator.Compatible interface

This commit adds Compatible to under xyz.openbmc_project.Decorator in
openbmc-dbus.json with property Names as described in
https://github.com/openbmc/phosphor-dbus-interfaces/blob/master/yaml/\
xyz/openbmc_project/Inventory/Decorator/Compatible.interface.yaml. This
commit also adds xyz.openbmc_project.Inventory.Decorator.Compatible to
under EMConfig in global.json so that the interface can be configured in
the board's Entity Manager configuration file. The usage of this
interface was mentioned in
https://github.com/openbmc/phosphor-dbus-interfaces/blob/master/yaml/\
xyz/openbmc_project/Software/README.md#compatibility.
