*Removing fake_platform environment variable. Following the merge of #9044 and Azure/sonic-swss#1978 the fake_platform environment variable is not used in any place and removing the stale references.

Added support for Mellanox-SN2700 based SKU for docker-sonic-vs and to differentiate platform based on hw-sku rather than on fake_platform in VS.
Currently SAI VS library uses hwsku based SAI profile to differentiate and mock different platform implementations. The same functionality in swss is achieved using a fake_platform env variable.
Using a fake_platform has some drawbacks that the vs container appears to still use a different vendor hw-sku

In order to unify the approach at both swss and vs SAI and to be uniform throughout this PR introduces the approach of using hw-sku to differentiate different platforms. This requires support for Mellanox-SN2700 HWSKU for Mellanox platform which is also addressed by this PR.

The orchagent and syncd need to have the same default synchronous mode configuration. This PR adds a template file to translate the default value in CONFIG_DB (empty field) to an explicit mode so that the orchagent and syncd could have the same default mode.
Add a master switch so that the sync/async mode can be configured.
Example usage of the switch:
1. Configure mode while building an image
`make ENABLE_SYNCHRONOUS_MODE=y <target>`
2. Configure when the device is running
Change CONFIG_DB with `sonic-cfggen -a '{"DEVICE_METADATA":{"localhost": {"synchronous_mode": "enable"}}}' --write-to-db`
Restart swss with `systemctl restart swss`
