avd: eos_designs incorrectely adds mtu 9214 for Mlag interface Vlan4094 on CCS-722/750

Issue Summary

switch models 722 and 750 do not support MTU settings per interface, but only global.

for example: eos_designs adds mtu 9214 to MLAG peer-interface VLAN4094, which is not supported on these platforms.

It throws an error message and MLAG will stay inactive.

Which component(s) of AVD impacted

eos_designs

How do you run AVD ?

Ansible CLI (with virtual-env or native python)

Steps to reproduce

just render mlag setting and push ist against two CCS-750/722 switches.
