Pull request overview

This PR upgrades Skiko from Kotlin 2.0.10 to 2.3.0, with substantial refactoring to support the newer Kotlin version. The PR is described as a test to investigate build failures on Linux in PR #1173, and adds the --allow-shlib-undefined linker option for Linux native builds.

Changes:

• Kotlin version upgraded from 2.0.10 to 2.3.0 across all modules and samples
• Web platform refactored to use standard kotlinx.browser and org.w3c.dom APIs instead of custom W3C declarations
• Build configuration updated to use compilerOptions instead of deprecated kotlinOptions
• Native C interop updated to use explicit unsigned literals instead of implicit conversions
• Import generator plugin enhanced to support both JS and WASM targets with WebImport annotation
• Android Gradle Plugin upgraded from 7.4.2 to 8.2.2
