Add AssignEndpointPreferred to allow callers to request a preferred EID for an endpoint. mctpd checks whether the requested EID is available before assigning it to the device. If the preferred EID is already in use, mctpd falls back to dynamic EID assignment. This is used by the MCTP reactor flow, where dbus-sensors reads the MCTPEndpointID property from Entity Manager and passes it to mctpd as the preferred EID. Update the README, mctpd documentation, endpoint recovery documentation, and tests for the preferred EID assignment flow.

Add AssignEndpointPreferred to allow MCTP reactor to request a preferred EID for an endpoint.
mctpd checks whether the requested EID is available before assigning it to the device. The policy for choosing preferred EID assignment or dynamic EID assignment is handled by MCTP reactor.
This is used with the MCTP reactor flow that reads the MCTPEndpointID property from Entity Manager and decides whether to request the configured EID or fall back to dynamic EID assignment.
Update the README, mctpd documentation, endpoint recovery documentation, and unit tests for the preferred EID assignment flow.
