Update Kotlin to 2.0.20 (#975)

Context receivers will be replaced by [1] and are deprecated for now,
so the CONTEXT_RECEIVERS_DEPRECATED warning must be suppressed in the
ksp-processors project.

The changes in the KLib ABI dumps are due to [2], constructors of sealed
classes aren't public ABI.

[1] Kotlin/KEEP#367
