Make parcelize work consistently with
`FirOverrideChecker`.
Actually, there is a philosophical question about
what to do when a plugin generates a class
in a new package, and this class is red code
(for instance, doesn't implement an abstract
member from a supertype). There's no source
to report such an error, but we probably do
want to run checkers to avoid trying to
compile red code to binaries (because it may
crash in backend, or it may silently work).
There is one of checks left unimplemented (FirParcelizePropertyChecker.checkParcelableClassProperty)
because it requires huge commonization of detecting which type can be
serialized and which not, which is not prioritized job for now
