ci: disable Kotlin Native incremental compilation in build workflow

- Update the full build command to include `-Pkotlin.incremental.native=false`.
- Update the FIXME comment to note that incremental compilation should be re-enabled along with the build cache after updating Kotlin beyond version 2.3.21.
