#### Description for the changelog
This change of removing hwsku.json is to correct the port index for
sfp ports (Ethernet0, Ethernet1, Ethernet2, Ethernet3) by using
port_config.ini, which should be '1, 2, 3, 4'. We could not do it
with hwsku.json, as it is defined as '5, 5, 5, 5' by platform.json
for the breakout_mode 1x40G[10G].

### Why I did it
Github issue: https://github.com/sonic-net/sonic-buildimage/issues/16356. The YANG definition breaks GCU feature.
We can either update sonic_yang and GCU's search algorithm to enable the same key count case or simply update YANG model to solve the issue.
The pros for update YANG model are it could solve the issue directly and we don't need to handle the complicate search algorithm in sonic_yang and GCU. This is the only YANG model that has this issue.
### How I did it
Combine two list into one. The previous YANG validation unit tests are still applicable.
#### How to verify it

The issue is related to #16812. Process syncd does not run in the container gbsyncd on kvm sonic with default hwsku.
Microsoft ADO : 26151608

- Why I did it
When module is totally under software control, driver cannot get module temperature/temperature threshold from firmware. In this case, sonic needs to get temperature/temperature threshold from EEPROM. In this PR, a thread thermal updater is created to update module temperature/temperature threshold while software control is enabled.

Update SAI version to SAIBuild2311.26.0.28
Fixed issues
1. Traffic with unicast destination ip and multicast destination mac wasn't properly dropped
2. When working with SAI_DEFAULT_SWITCHING_MODE_STORE_FORWARD key/value enabled, trying to add a LAG member to a LAG which is created after warm boot initial configuration phase ended, will fail.
3. Optional feature of Port IP counters (SAI_PORT_STAT_IP*) , enabled by SAI XML per-port-ip-counter-enabled config node, wasn't initialized properly.
4. Creating BFD session for non default VRF fails (SAI_BFD_SESSION_ATTR_VIRTUAL_ROUTER != SAI_SWITCH_ATTR_DEFAULT_VIRTUAL_ROUTER_ID).
5. The default value for port FEC during switch init for Spectrum3 was initialized as 'auto' and not aligned to SAI header default 'none'. Note if setups has invalid configuration and relied previously on auto, now it might be necessary for the user to provide explicit valid value for SAI_PORT_ATTR_FEC_MODE
Update SDK/FW version to 4.6.2134/2012.2134
Fixed issues:
1. Updated SN3700C to enable limit to 100G speed.
2. Recovering from Low power mode might ends with port down.

### Why I did it
Current YANG model of sonic-events-swss:chk_crm_threshold has the type uint8 for leaf used_cnt which is too small of a range to hold values of used_cnt which can greatly exceed that. Updating leaf type of used_cnt and free_cnt to match defined definition.
Changed to uint32 as per defined here: https://github.com/sonic-net/sonic-swss/blob/master/orchagent/crmorch.h#L99
