Consider callable reference's LHS when resolving RHS

Previous resolution sequence (static scope, nested classes scope, receiver) and
a check against type parameters only made sense when there's a type, not an
expression, on the LHS of a callable reference. Also TransientReceiver is
incorrect in such case because private-to-this visibility check only works for
ExpressionReceiver values
