- While `collectionInitializationInfo` unwrapped a script's top-level
declarations, `check` forgot to do it, so a script effectively had no
top-level properties in the mind of the checker.
^KT-63286 fixed
- The test data is missing initialization checks and will be fixed with
the subsequent commit.
- The test data is originally taken from
`backingField/TopLevelPropertyInitialization` and has been simplified.
- I didn't add `const val` properties to the test data (compared to the
original) due to KT-20110.
