Why I did it
Arista-7260CX3-Q64 is missing T1 MMU configuration.
How I did it
Define T1 MMU configuration for Arista-7260CX3-Q64.

* 7260cx3 DualToR config.bcm support based on DualToR setting in device metadata at boot time.
For HWSKU Arista-7260CX3-C64 the MMU setting SOC for T0/T1 is also combined into the config.bcm.j2 logic so use just one config file and adding delta based on Switch Roles.
