Feat(eos_designs): Disable per interface MTU for 7010TX

[xaviramon]

Change Summary

On the 7010TX platform, not using the per_interface_mtu: false setting, will generate an incorrect MTU configuration in some interfaces, which is not supported on T3.x1, x2 and x4. This brakes MLAG configuration on these devices.

This is not considered a breaking change since using the defined platforms today generates a broken configuration.
