Alexander Udalov 6cc293a0c5 JVM IR: record FIELD_FOR_PROPERTY for property delegates
Delegated properties now have their $delegate fields recorded in the
metadata (in `ClassCodegen.generateField`). This part of metadata is
used by `KPropertyN.getDelegate` functions, so almost all tests on
getDelegate are now unmuted
