Add support for SMEMBERS.WATCH command

[JyotinderSingh]

Add support for reactive queries on the existing SMEMBERS command by introducing SMEMBERS.WATCH.

This command should send push-responses to subscribed clients whenever the data inside the respective hash set changes.

As a part of this feature, you are also required to add support for the same to the dicedb-go SDK inside the watch_command.go file.

Reference

1. You may refer to Adds support for ZRANGE.WATCH #1047 to understand the changes required to support this command.
2. Implements Command Watch Manager and Adds GET.WATCH Command Support #924 provides more background on the feature's underlying implementation (but may not be directly relevant to this issue)

Testing

1. Ensure integration tests are added, you can refer to existing .WATCH integration tests.
2. Integration tests should include both resp tests and SDK tests.
