[FIR] Resolve value class constructor to TYPES before using its params

Right now it is the easiest way to ensure that all the parameters are
resolved. After KT-53573 is fixed, we might use `resolvedReturnTypeRef`
on each parameter individually instead

Also, add `toString` implementation to `ValueClassRepresentation`
classes, so they are properly rendered in testdata
