Add support for Kotlin 2.2+ with versioned artifact system

Kotlin 2.2 removed trove4j and android-extensions jars from the distribution.
This change introduces version-specific artifact definitions (artifacts_2.1.bzl
and artifacts_2.2.bzl) to handle these differences, with automatic selection
based on Kotlin version. Updates default Kotlin version to 2.2.

Changes:
- Created WriteKotlinArtifacts tool to generate artifact definitions
- Added artifacts_2.1.bzl (includes trove4j) and artifacts_2.2.bzl
- Updated compiler.bzl to use KOTLIN_STDLIBS from artifacts
- Updated default Kotlin version to 2.2.21
- Added custom_compiler_version example to test backward compatibility
- Updated jdeps plugin imports to use K2 FIR APIs

Fixes #1373
