Bug#1057513: kotlin: FTBFS with default Java 21

[Vladimir Petko]

Dear Maintainers,

 Would it be possible to consider merge requests [1][2][3] that
address the issue?
 Kotlin needs to be rebuilt before introducing Java 21 default as it
vendors asm library and it needs to be updated before switching to
Java 21 default.
Due to the update to minimum supported source level 8, AbstractList
and Collections now declare toArray() methods that I had to add via
the patch. This introduces API incompatibility (Debian kotlin having
extra methods).

Best Regards,
 Vladimir.
