LibJS: Define constructor slots for describing how to read options

This is an editorial change in the ECMA-402 spec. See:
a2beb66

We implement this change by introducing a virtual interface that all
Intl "service" objects must implement. A future patch will make use of
the virtualized RelevantExtensionKeys and ResolutionOptionDescriptors
accessors, and we will need to be able to use those slots from a generic
instance type.
