Subject: [PATCH] [Arista] Enable larger number of LAGs on 7800 LCs (#11070)

For 7800 LCs, set LAG mode to support 1024 number of 16-member system
LAGs.

Why I did it
The SOC property changes are necessary to match #10519 which increases the number of system LAG IDs to 1024.

Description for the changelog
For 7800 LCs, set LAG mode to support 1024 number of 16-member system
LAGs.
