[Ada] Missing tagged type decoration in corresponding record subtypes

The frontend silently skips propagating attribute Is_Tagged_Type to the
constrained corresponding record subtype associated with a protected
type or task type with discriminants. This change does not affect the
functionality of the compiler; it leaves more clean the decoration of
internal entities.
