#### Why I did it
Fixing https://github.com/Azure/sonic-buildimage/issues/8938
Fixing 1x10G DPB mode in Mellanox-SN2700-D40C8S8 SKU as it was causing sonic-cfggen to fail.
#### How I did it
Added correct mode format in hwksu.json in Mellanox-SN2700-D40C8S8 and updated platform.json for the new mode.
#### How to verify it
Using sonic-cfggen verify it works fine
- Why I did it
To create SDK dump on Mellanox devices when SDK event has occurred.
- How I did it
Set the SKUs keys needed to initialize the feature in SAI.
- How to verify it
Simulate SDK event and check that dump is created in the expected path.
Fix to the correct value for all SPC1 devices.
For 10G added 10GB_CX4_XAUI, 10GB_KX4, 10GB_KR, 10GB_SR and 10GB_ER_LR
For 50G added 50GB_SR2
This bitmask represents all the options available for interface type and some were missing.
Note: it was working just fine if you were setting the value from SONiC CLI but not from the default SAI Profile.
