Before this commit, we added Enum.entries only in case when
LanguageFeature.EnumEntries was ON (with an exception in K1/Java case).
In this commit we add Enum.entries unconditionally, and in case
the language feature is OFF we filter them out during tower resolve.
Namely, remove incorporation “otherInsideMyConstraint” to eliminate
constraint system redundancy and produce a potentially very large number
of constructs.
Instead, introduce not so “spreadable” incorporation during variable
fixation (equality constraint with result type into other constraints).
