[Mellanox]Update SAI to 2311.26.0.28, SDK/FW to 4.6.2134/2012.2134

[dgsudharsan]

Why I did it

Update SAI version to SAIBuild2311.26.0.28

Fixed issues

• Traffic with unicast destination ip and multicast destination mac wasn't properly dropped
• 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.
• 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.
• Creating BFD session for non default VRF fails (SAI_BFD_SESSION_ATTR_VIRTUAL_ROUTER != SAI_SWITCH_ATTR_DEFAULT_VIRTUAL_ROUTER_ID).
• 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:

• Updated SN3700C to enable limit to 100G speed.
• Recovering from Low power mode might ends with port down.
