Previously, creating a declaration with Fir2IrCallableDeclarationsGenerator/
Fir2IrClassifiersGenerator didn't guarantee that this declaration will
be actually added to the list of parent class/file declarations, which
lead to situations when FIR2IR created some declarations in the air
(mostly fake-overrides)
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.
The changes to the irText test data result in the fact that we
now unconditionally unwrap substitution overrides of delegation targets
whereas before we built an unsubstituted scope of the type we delegate
to. If we delegate to a class A : B<C>, the unsubstituted scope of
A can still contain substitution overrides for inherited generic methods
from B<T> that we didn't unwrap before but do unwrap now.
