This change is to disable the pcie firmware check done by Broadcom SAI. The change is needed for the Arista platform x86_64-arista_7050cx3_32s; otherwise, the check will fail, blocking the initialization.
There was a pcie firmware check added in brcm SDK and certain Arista hardwares do not compliant with the check, so we added the disable_pcie_firmware_check originally for x86_64-arista_7060dx4_32. For x86_64-arista_7050cx3_32s, it was able to pass the check but some firmware change done in August made it fail.

* Set sai_tunnel_underlay_route_mode attribute to fallback to default route if more specific route is unavailable.

Why I did it
To support dynamic port breakout Broadcom configurations on Arista platforms.
How I did it
Updated platform.json for platforms and added new hwsku, Broadcom config, and hwsku.json for dynamic port breakout usage.
The name of the new hwsku name used is very similar to the platform name (platform x86_64-arista_7050_qx32s hwsku Arista-7050QX-32S) as the flex hwsku is meant to be the default in the future.
How to verify it
Boot up device with the new hwsku, interfaces are up.
Change hwsku.json with new default breakout mode and reload device, breakout will have successfully been applied.
