Replace two other, imperfect mechanisms for use-def tracking. Use ValidationState_t::entry_points to track entry points. Concentrate undefined-ID diagnostics in a single place. Move validate_types.h content into validate.h due to increased inter-dependency. Track uses of all IDs: TYPE_ID, SCOPE_ID, ... Also update some blurbs. Fix entry-point accumulation and move it outside ProcessIds(). Remove validate_types.h from CMakeLists.txt. Blurb for spvIsIdType. Remove redundant diagnostics for undefined IDs. Join "can not" and reformat.
