Add new enum to support 8 lanes breakout mode

[rajkumar38]

Add new breakout mode enum to "sai_port_breakout_mode_type_t",

/** 8 lanes breakout Mode */ SAI_PORT_BREAKOUT_MODE_TYPE_8_LANE = 3,

@kcudnik Can you suggest how to fix this WARNING ? I'm excluding "SAI_PORT_BREAKOUT_MODE_TYPE_MAX " in ancestry.pl.

WARNING: Both enums have the same value SAI_PORT_BREAKOUT_MODE_TYPE_8_LANE and SAI_PORT_BREAKOUT_MODE_TYPE_MAX = 0x00000003

You need to add exception for max value in checking script

@JaiOCP, Regarding your question on standards. There are different IEEE 802.3(https://en.wikipedia.org/wiki/Terabit_Ethernet) standards for defining Terabit Ethernet with different speeds. This captures the max lanes and speed per lane but doesn't explicitly talk about break-out. Its up-to vendor capability.
