API to get serializer for a class without creating kotlin reflection class

See original GitHub issue

What is your use-case and why do you need this feature?

Current experimental API ::kotlin.get().serializer() implies creating extra kotlin reflection class. That’s not acceptable from a performance point of view in all cases.

Describe the solution you’d like

Could you please provide API to use just a java Class?

In the new release,it should be enough to use Type-based functions, they avoid instantiating KClass as much as possible

Let me rephrase it directly: consider we have an API Class<?>.serializer() which mirrors KClass<?>.serializer() – supports all the types the latter does, instantiates KClass for polymorphic serializers and does all the checks required for API to function – whether the class is enum, interface and so on, will such API be useful for you? Are you still going to adopt it?
