K2: Fix deserialization of upper bound of type parameter in nested class

Previously, containingDeclarationSymbol for V was set to the outer class
BaseRoot, so its upper bounds was computed to the ones from TNested
at org.jetbrains.kotlin.fir.resolve.calls.CreateFreshTypeVariableSubstitutorStageKt.getTypeParameterFromExpandedClass
