Build improvements: Kotlin 1.9.20-RC, default target hierarchy, bump Okio (#2473)

* Build improvements: Kotlin 1.9.20-RC, default target hierarchy, bump Okio

Updated to Kotlin 1.9.20-RC:
- Kotlin 1.9.0/10 had some blockers in XCode 15 support.
- Simplify WASM setup (it has been changed in 1.9.20).
- Drop obsolete Native targets

Apply default target hierarchy:
- Greatly simplified buildscript for native targets.
- Supported targets are now runnable from gutter in the IDE.
- Now all possible targets are built by default (without -Pnative.deploy flag), resulting in less confusion for contributors and CI (but longer local `check` times).
- Publishing library with K2 should be possible now, no more incorrect `publishNativeKotlinMetadata` failing task.
- More targets available in integration-test project.

Updated Okio for:
- linuxArm64 target support
