[Tunnel PFC] Add property for tunnel PFC (sonic-net#10962)

* [Tunnel PFC] Add property for tunnel PFC

Replace the config.bcm file with j2 template file
- Add 'sai_remap_prio_on_tnl_egress=1' property when device metadata local
- Host subtype is 'dualtor'
- Change sai.profile foe the new config.bcm.j2
