Simplify and fix createReflectionTypeForCallableDescriptor

Previously its call sites needed to determine if the receiver type should be
ignored (e.g. if the reference is to static member or nested class constructor,
or if it's a bound reference), and 3 of 4 callers did it incorrectly. Simplify
this by passing the DoubleColonLHS instance everywhere.

Also rename it to createKCallableTypeForReference
