[DPB][YANG] extended yang-model - added 'buffer_model' field, added test cases (#6464)

Browse Source 
- Why I did it
The fix for the issue [DPB][YANG] sonic-device_metadata.yang is not aligned with newest changes in CONFIG_DB

- How I did it
CONFIG_DB was extended with the field buffer_model - added representation of this field inside the sonic-device_metadata.yang

- How to verify it
Run the command config interface breakout <interface> <breakout_mode>
