DPB does not remove the newly created ports from default vlan 1#4139

Description:
We currently do not remove the newly created breakout ports from default vlan after it is created(By design, SONiC switch starts with all bridge ports removed from default VLAN and all ports removed from .1Q bridge).

As the result of this, in subsequent warmboot with DPB in config, when we query the default vlan we get new ports as members of vlan 1. When we remove them, vendor SAI assumes that this port is no longer participating in any other vlan.
BCM SAI - 13.2.1.24
SONiC - 202505/master

Details:

  1. breakout 1 800G port on TH5 to 2*400 using DPB CLI and config save
  2. config L3 and start IP traffic
  3. warmreboot
    traffic never gets restored

In # 1 when new ports are created by design SAI add them as untagged members to VLAN 1. Ideally all new 400G ports should have been removed from default vlan 1 after create port(before RIFconfig).

In # 3 during warmboot by design, all the new 400G ports are removed from default vlan 1 and vendor SAI assumes that these ports are not participating in any vlan anymore.
