[CSBindings] Determine literal coverage and default types during finalization
[CSBindings] Determine literal coverage and default types during finalization

Based on collected direct and transitive information about protocol
requirements let's determine literal protocol coverage by existing
bindings as well as any default types which have to be introduced
to the set as part of finalization phase.
