This doesn't reduce the quality of tests, because the flags are still
printed for declarations themselves. We only omit them in references.
However, this makes the tests more compatible with non-JVM backends
(see KT-58605), because flags of referenced stdlib declarations may
differ among target platforms.
Previously, the semantic was more-or-less correct for most of the cases
but some corner one, like `sort` in MutableList didn't work properly.
Namely, `sort` should be marked there in a way to forbid to call it
everywhere beside super-calls.
Also, overriding it should be allowed.
Mostly, the logic was re-written to K2 model from K1-related
JvmBuiltInsCustomizer.
^KT-57694 In progress
^KT-57269 Fixed
Use the same condition as in the already existing `createIrEnumEntry`
function (and as in psi2ir): enum class should be final unless there's
an enum entry with any declaration other than its constructor.
#KT-57216
This change allows to revert adding `WITH_STDLIB` directive
to tests which happened at `a9343aeb`.
