Add mctp eids configuration for Yosemite 4

The MCTP specification is defined in DSP0236. As describe in section
8.17.2, we need a configuration for static EIDs. The `mctpd` from
CodeConstuct/mctp will be able to know where those static EIDs located.
The other services will be able to know what those EIDs stand for by the
"Name" as well.

schemas: add `EndpointId` with type `string` and `number`.

Tested: check D-Bus path for configuration.
