Use abstract factory for reflection objects on JVM

Browse Source 
Introduce an abstract factory class ReflectionFactory which is responsible for creating
reflection objects (KClass, KProperty, ...). The meaningful implementation is
located in "reflection.jvm" where KClassImpl/KPropertyImpl/... are accessible
and can be instantiated. The default implementation will be used in the lite
runtime with no reflection and will return nulls / throw exceptions there.

Put all functions, calls to which are generated by JVM back-end, in one place:
the class named Reflection which contains only static methods. Previously these
functions were scattered across different files in module "reflection.jvm".

The code using reflection may now be compiled against either runtime, but
reflection features will work if and only if reflection is accessible at
runtime
