Why I did it
To fix ecmp hash polarization issue.
Work item tracking
Microsoft ADO (number only): 26085143
How I did it
Add sai_hash_seed_config_hash_offset_enable=1 in all config.bcm that Broadcom T1 uses.

8.4.35.0: [CSP 00012324019] back-porting SONIC-75006 to SAI8.4
8.4.34.0:
[CSP 00012318293] back-porting SONIC-81534 to SAI8.4;
ECMP LB traffic polarization, configure hash_offset along with hash_seed attr
Run qual with only xgs SAI version upgraded to 8.4.35.0:

QOS tables in config db used ABNF format i.e "[TABLE_NAME|name] to refer fieldvalue to other qos tables.
Example:
Config DB:
"Ethernet92|3": {
"scheduler": "[SCHEDULER|scheduler.1]",
"wred_profile": "[WRED_PROFILE|AZURE_LOSSLESS]"
},
"Ethernet0|0": {
"profile": "[BUFFER_PROFILE|ingress_lossy_profile]"
},
"Ethernet0": {
"dscp_to_tc_map": "[DSCP_TO_TC_MAP|AZURE]",
"pfc_enable": "3,4",
"pfc_to_queue_map": "[MAP_PFC_PRIORITY_TO_QUEUE|AZURE]",
"tc_to_pg_map": "[TC_TO_PRIORITY_GROUP_MAP|AZURE]",
"tc_to_queue_map": "[TC_TO_QUEUE_MAP|AZURE]"
},
This format is not consistent with other DB schema followed in sonic.
And also this reference in DB is not required, This is taken care by YANG "leafref".
Removed this format from all platform files to consistent with other sonic db schema.
Example:
"Ethernet92|3": {
"scheduler": "scheduler.1",
"wred_profile": "AZURE_LOSSLESS"
},

Treat devices that are ToRRouters (ToRRouters and BackEndToRRouters) the same when rendering templates
Except for BackEndToRRouters belonging to a storage cluster, since these devices have extra sub-interfaces created

However in SAI 3.7 default behaviout got changes to 128 Group and 128
Memeber each.
This change is to make sure we are using same ECMP Group/Memeber Per
Group for 3.7 also so that behaviour is consistent.

Dynamic threshold setting changed to 0 and WRED profile green min threshold set to 250000 for Tomahawk devices
Changed the dynamic threshold settings in pg_profile_lookup.ini
Added a macro for WRED profiles in qos.json.j2 for Tomahawk devices
Necessary changes made in qos.config.j2 to use the macro if present

* Remove the divide by 4 operation to the under the hood SAI
This is to avoid the need and thus the confusion for application program to know
the mmu internal architecture
This change must have support from SAI change to reach the correct
config
