CfW: Prevent UnpackSkikoWasmRuntime task execution when it's not need…

…ed (#4824)

Fixes: #4823

In #4796 we
intentionally started to configure the web app for all k/js and k/wasm
targets. The configuration involves adding a dependency on skiko-wasm
runtime and unpacking it.
Some projects don't need skiko-wasm-runtime (like those based on
compose.html or just compose.runtime).

**Solution:**
We check if there is a dependency on org.jetbrains.compose.ui libraries
(including transitive dependencies). If we find it, then we enable
skikoUnpack task. Otherwise it's disabled.

## Testing
- Build the gradle plugin locally (with this change)
- Used it in our html landing example:
https://github.com/JetBrains/compose-multiplatform/blob/master/examples/html/landing
- Run `./gradlew jsBrowserDistribution`, check
`.../compose-multiplatform/examples/html/landing/build/dist/js/productionExecutable`
and see NO skiko.* files added there
- Then add `implementation(compose.foundation)` dependency in
build.gradle.jts and run `./gradlew clean jsBrowserDistribution` again -
the build/dist contains skiko.* now
