[AND-171] Refactor call service config

[rahul-lohra]

🎯 Goal

Problem Statement: SDK Users need to re-initialize stream sdk to change/update call configuration
This PR presents solves this by allowing the users to update call configuration any time

🛠 Implementation details

We introduced a new class CallServiceConfigRegistry to hold the mapping for call type with call configuration

It exposes the following apis

Registering Configurations:

    val registry = CallServiceConfigRegistry()
 
    // Register a configuration explicitly
    registry.register(CallType.Default.name, CallServiceConfig())

    // Register a configuration using a builder
    registry.register("livestream") {
        setServiceClass(MyCallService::class.java)
        setRunCallServiceInForeground(true)
    }
 
    // Register multiple configurations using a map
    registry.register(
            mapOf(
            CallType.AudioCall.name to CallServiceConfig(),
            CallType.Default.name to CallServiceConfig()
        )
    )

Retrieving Configurations:

   val config = registry.get(CallType.Default.name)

Updating Configurations:

    registry.update(CallType.Default.name) {
         setRunCallServiceInForeground(false)
    }

CallServiceConfigRegistry is exposed via ClientState
