KT-39788 MPP, Gradle runner: Run does not add resource directory to classpath // classpath fix

Browse Source 
The reason of resource directory absence was that it couldn't be loaded
from the project configuration file. Just after the import it remained
in the memory and runner couldn' get it. KotlinOutputPathsDataService as
a pair to KotlinOutputPaths is what was missing. Details are provided
below.
------------------------------------------------------------------------
On a disk configuration represents a binary file containing serialized
graph of external project structure. It contains nodes belonging to both
IDEA and its plugins.

To deserialize a node IDEA tries to load its class using a chain of
class-loaders: its own and those provided by actual set of plugins.
The nuance is how to get plugins' ones. The approach is the following.
There is an association between a node's payload and a service which is
supposed to consume it see KotlinOutputPathsDataService#getTargetDataKey
and DataNode#getKey). Plugin services are guaranteed to be loaded by
plugin class loader.
No association - service - no plugin, node was just skipped.
