TypeRegistry is the static map which contains mapping between type of
session component and its index in the session array. Originally
`KClass` of a component was used as a key in this map, which worked
pretty well for compiler components. But there was a problem with
components from plugins and Kotlin daemon: in compilation with daemon
we keep TypeRegistry between compilations. But for each compilation
we load plugins from jar, which brings to the situation when after N
compilations there is N entries in TypeRegistry map with different
KClass'es for same extension component. This not only causes AIOBE
but also introduces the memory leak, because we keep reference to
KClass which is not used anymore
So to fix this issue it's enough to just store FQN of component in
TypeRegistry instead of KClass
There are no tests in this commit, but they will be added in next
commit relevant to scripting. With those commits we will have gradle
integration tests which uses Kotlin compiler daemon and registers
a compiler plugin for scripting
