Network: Add support for MTU propery

This commit adds support for the MTU property under
the "xyz.openbmc_project.Network.EthernetInterface" interface.

This property shows the maximum size of the Protocol Data Uint
(PDU) in bytes, that can be passed in an Ethernet frame on the
network interface.

Tested:

Verified this property on "xyz.openbmc_project.Network.EthernetInterface"
interface.

busctl introspect xyz.openbmc_project.Network /xyz/openbmc_project/network/eth3
