Identify and complete facet types as needed for p5168 (#6369)

Browse Source 
Proposal #5168 defines when a facet type must be identified or complete,
and what it means for an interface and a named constraint to be
identified or complete. This updates the toolchain to match the
requirements.

This implements identification of a facet type to require completed
named constraints and to include any interfaces from named constraints
into the resulting IdentifiedFacetType.

To complete a facet type, each interface in the IdentifiedFacetType, and
any interface named though a require declaration from them, must be
complete.
