chore: Improve Filter API to provide sharding specific ContentFilter options

[chaitanyaprem]

Background

Provide an option for users to specify or choose the type of ContentFilter they want to use as per the type of relay-sharding required by the application (Named, Static or Auto sharding)

Details

Improve the devEx by providing option for users to specify which type of ContentFilter they want to use.
Users can specify AutoShardingContentFilter (which only accepts contentTopics) or NamedStaticShardingContentFilter(which accepts both pubSubtopic and a list of contentTopics). This would prevent misuse of API and running into issues.

Refer discussion here

Acceptance criteria

All following API's should be modified to accept new shard specific contentFilters

• Go API
• mobile API
• c-bindings
