ethtool: T7730: Add configuration coalesce for interface

This change introduces CLI support for configuring network interface
interrupt coalescing parameters via `netlink`.

Note: Not all NIC drivers support interrupt coalescing. On unsupported interfaces,
`netlink` returns an error and the VyOS commit will fail.
